I would like to raise a complaint about Karvl.com and @perfectip
Before explaining my issue, I need to provide some background regarding Karvl’s billing rules.
Karvl charges $1 per 100GB for traffic usage exceeding the included allowance, and Karvl’s billing date is the first day of each month.
On July 13, 2026, my Karvl server went offline. When I logged in, I was informed that I had an outstanding bill of $28.
I wanted to access my account to ask what had happened. However, Karvl does not allow users to perform any account operations unless the outstanding bill is paid. Even submitting a support ticket is not permitted while there is an unpaid invoice.
I have server monitoring in place, and the monitoring data clearly shows that my server usage did not exceed the included traffic allowance. Since the billing date is the first day of each month, my usage from July 1 to July 13 was nowhere near the allocated limit.
I therefore registered a second account and submitted a support ticket. I provided the email address associated with my first account, the specifications of the server I had purchased, the amount of the outstanding invoice, and previous transaction and order numbers.
Despite providing all of this information, support told me that I had to contact them by email using the email address associated with my first account.
I explained that I could not contact them from that email address because the email account was no longer accessible.
Karvl then directly deleted my second account!
Why are users prevented from submitting support tickets unless they first pay an outstanding invoice?
Why was I incorrectly billed?
Why was my second account deleted immediately after I registered it to report this issue?

Not letting people submit tickets in case of billing disputes is a shitty practice but you basically fucked yourself here by not keeping your client data up to date. If you had a current email on file you would have able to contact them after all but since you didn't you'll have to deal with the consequences.
Also are you sure your monitoring actually includes all traffic (like ARP, random broadcasts, etc)? Those can add up to quite the amount depending on the specific configuration.
Edit: The account was deleted since without hard proof (which you can't provide) of you actually being the owner of the original account there's really nothing they can do. Knowing a bunch of numbers doesn't really proof all that much.
How anyone should asses if you were billed incorrectly is beyond me. No one has access to any data whatsoever concerning your traffic.
I have considered a possible explanation for this issue: perhaps the billing date and the traffic allowance reset date are different.
However, that would still be extremely unusual. What service provider separates the billing date from the date on which the monthly traffic allowance resets?
Regarding the email issue, I normally use temporary email addresses when registering with service providers because I do not want my main inbox to be filled with promotional or spam emails.
I am confident that my monitoring system includes all traffic, because the usage measurements across all of my servers have always been accurate.
In fact, I also provided support with another important piece of information: both of my accounts were accessed from the same IP address.
I can provide the PayPal transaction ID.
I can provide the exact amount of the invoice.
I can provide the specifications of the server I purchased.
Both accounts were even accessed from the same login IP address.
I honestly do not know what else I could provide to prove that I am the legitimate owner of the account.
I purchased a plan that included 5TB of monthly traffic. My server monitoring software showed that I still had 784GB remaining.
However, I was charged $28. Since Karvl charges $1 per 100GB of excess traffic, this invoice suggests that I exceeded my allowance by 2.8TB.
That is an extremely large discrepancy.
No one besides the host could realistically know that.
That's a great practice... if you don't like having a recourse after - for whatever reason - getting locked out of the account.
OK.
For all they know it could be some public system. Security protocols exist for a reason.
That's certainly something but you are still asking them to skip the usual verification process and the professional option is to stick to protocols.
Yeah, you probably would have been better off setting up a filter to autobin potential newsletters. At this point the ball is pretty much in their court. Maybe ask them if they would be willing to authenticate you by KYC (assuming you at least have correct data on file).
Or just pay and try to clear it up afterwards. If it doesn't work out i'd take it as a (costly) reminder that keeping records up to date is a good thing.
That's true but like i said a couple times already no one is able to verify any of that one way or the other.
10/10 would visit again.
perfect tip
Never heard of them.
Karvl is also active on this forum, and I genuinely hope that after seeing this post, they will make some improvements.
First, users should still be allowed to submit support tickets when they have an overdue invoice.
Second, the billing rules should be clearly explained in the Terms of Service. In fact, about two months ago, I submitted a ticket asking about the promotional credit given to new users. However, the response was also extremely vague, and I could not understand the rules at all. At that time, I already felt that something was not quite right.
In my original post, I said that the invoice amount was $28, but it was actually $29. Why was there a discrepancy?
Because the invoice amount keeps changing dynamically, and in a very confusing way.
The latest time I checked, the overdue invoice had dropped to $24.
The amount decreases slightly from time to time.
This is really strange.
Yeah but that is pretty much the only thing i agree on here.
Might have been a hint to look elsewhere.
WTF? What are you going about now.
You might want to discuss that with your host.
Yes it is but so is your disinterest to get your account in order.
This whole thread is sketchy by not providing necessary info. So annoying. What panel is being used? Post screenshot of the tickets being disabled and the VPS panel being inaccessible.
Post the invoice. If it's overdue and service disabled, it's because the period is over and so saying you have time left doesn't make sense if the period is June.
Provide invoice date, due date, and description of the amount and period covered.
Lastly, are you accounting for both in and out adding up and not just one direction? What is the management software?
First, Karvl’s billing date is the first day of each month, and its services are billed hourly.
Second, I am unable to provide a screenshot showing that ticket support was disabled because there is no message explicitly stating that support has been disabled. Whenever I click on the support ticket section, I am automatically redirected to the invoice payment page. As long as the outstanding invoice remains unpaid, I am not allowed to use any account functions.
Third, regarding the bandwidth usage, you can see from the image at the top of the thread that the server name shown on the left only states “2.5TB one-way traffic.” On the right, the actual usage is calculated bidirectionally: 4.2TB used and 782GB remaining.
I understand the common convention that, unless otherwise specified, traffic is calculated in both directions.
Right, so an invoice on July 1 is for usage in June, not July. Or since its past due, maybe even May usage. Post the invoice, you're not making sense.
It helps having headers to explain shit. I have no idea what the red and green bars indicate (red is generally bad) wrt to 4.2GB and 5.7GB and percentages used, but it seems flawed to show total when you can exceed one direction and be charged. I feel like that is your problem.
What is the monitoring software and what bandwidth totals has it given you?
Let me lay out the full timeline, as my previous explanation may not have been clear enough.
I purchased two servers from Karvl:
Karvl generates invoices on the first day of each month, and I already paid the June invoice on July 1.
Karvl charges $1 for every additional 100 GB of traffic.
On July 13, 2026, both of my servers went offline. My account showed an unpaid invoice of $28, and I was told that I had to pay it before I could use any account features again.
However, as shown in the monitoring screenshots included in my original post, between July 1 and July 13, my Japan server was barely used. My Singapore server had used 4.2 TB of traffic and still had 782 GB remaining.
In other words, there is a discrepancy of approximately 3.5 TB between the traffic shown by my own server monitoring system and the usage recorded on the invoice. That is absurd, isn’t it?
Also, I believe you misread the screenshot. The server on the top row is the Singapore server, showing 4.2 TB used. The server below it is the Japan server, showing 5.7 GB used.
It is 4.2 TB and 5.7 GB, not 4.2 GB and 5.7 GB.
Finally, I just checked my billing page again, and the latest invoice has now changed from $28 to $22. The amount appears to be slowly decreasing over time.
This is extremely strange. I have genuinely never seen a billing system behave like this before.
5TB or 2.5TB "one way"? Which one is it? I've never seen anyone put 2.5TB "one way" to mean 5TB.
5 TB of bidirectional bandwidth, which is equivalent to 2.5 TB each way. That’s just how I personally track bandwidth usage.
2 servers, down to 1 just few days ago so it will count on July bill I guess.
I am not defending them, I am also unsure about how they bill, but it never went overhead so far.
TLDR;
Avoid Karvl.
What sort of bullshit is this?
I've only seen this once before, and it was some obscure regional newspaper website for an APAC country. Like, I can't imagine any reason any site would need that.
There's a large computer manufacturer that also has that feature, or at least had, for their auto detection tool for updates
It's funnier. There is some random badly entered (WYSIWYG wordpress?)
that decimal/hex-v4 resolves into a 0.0.* IP
That's kind of fucked. 5TB of general traffic is just 5TB of traffic. It hardly ever evens out. Usually there's way more out than in, so your 2.5 each are more likely to look like 1 in 4 out in the real world.
What I mean is that writing “2.5 TB” is just my personal naming habit. It has nothing to do with the server’s actual traffic statistics. It’s simply the server’s name, and I can change it to whatever I want. I could call it “iPhone 99 Pro Maxxxxxx 9999 TB” if I felt like it.
Yes, you can but it would still be fucking weird, confusing and absurd.
It makes sense if the server is being used for any kind of symmetric relaying of traffic (WireGuard tunnels, etc).
Hey, I’m not sure why, but I was suddenly able to log in again, and both of my Karvl servers are online now.
The screenshots above show my bandwidth usage for the past 30 days and the past 14 days.
My Japan server has 1 vCPU, 1 GB of RAM, and 10 TB of bandwidth. My Singapore server has 1 vCPU, 1 GB of RAM, and 5 TB of bandwidth.
The bandwidth overage rate is $1 per 100 GB, and billing is calculated on the first day of each month.
As the screenshots clearly show, my usage since the first of this month has not exceeded my included bandwidth allowance.
Even if Karvl issues invoices on the first of every month while calculating bandwidth usage in a rather unusual rolling 30-day period starting from the purchase date, my Singapore server has still used only 7.04 TB.
There is no reasonable way this should result in a $28 overage charge. A $28 charge would mean that I used 2.8 TB beyond the included 5 TB, for a total of 7.8 TB. That does not match the 7.04 TB displayed in the server control panel.
What makes this even stranger is that the charge was originally $28, but it has now dropped to $21.50. The amount appears to decrease slightly every day.
I was not lying or trying to mislead anyone. There is genuinely something wrong with Karvl’s billing system.
Could it be that the monthly bandwidth allotment is accrued in daily increments? So it won't let you consume the whole month of bandwidth in 1 day or 1 or 2 weeks?
That might explain why the overage charges are decreasing, also, as the bandwidth allotments are accrued.
Screw the system being wrong or you being wrong, $1 per 100GB, what are these prices absolutely insane
No, I don't need that for a third time, just what the invoice is showing.
Yep, misread, thank you for catching that. So it shows remaining bandwidth.
Yeah, sounds like they have a processing bug is confirmed. If only we had each version of invoice...
Maybe you're right,.
I think I may have figured out how this billing system works.
A bill is issued on the first day of each month, and then the system estimates the next month's bill based on your average daily usage.
If the estimated monthly bill exceeds $30, the account gets locked, and you have to pay the bill before you can continue using any of the features.
If you stop using the server afterward, your average daily usage will gradually decrease, so the estimated bill for the following month will also keep going down.
This is the only reasonable explanation.
If this is really how it works, then it's a terrible system—especially because it requires users to pay for usage they haven't actually incurred yet, and locks their accounts if they don't pay.
What's even worse is that once the account is locked, you can't use any features at all, including submitting a support ticket.
I still don't understand why you won't post the invoices, but whatever. Also, that you don't understand the billing you've signed up for.
As per their website, you just send them an email if you can't make a ticket. You're being facetious because it's actually YOUR fault with some sort of account swap shenanigans. Don't mislead people.
