Hello Guys,
I can list of many reasons to stay away from this company.
1) Totally illegal financially:
Due to their illegal activity in financing procedure, I had to contact sub-department of "German Federal Ministry of Finance" ( abbreviated as BMF ). They charge VAT to non-EU members but after your payment, they do not indicate VAT in submitted invoice. Do not feed this gangstas with your money.
2) There is no way to cancel your service:
I signed up to their website and checked out a dedicated server with one month subs. I did not choose annual subscription, that's why monthly price was a bit higher. Before the end of three months period, I informed them that I did not need this service and thanked them.
What happened next?
They asked extra money in addition to given price in their website. In case you do not agree with their price, they threaten you by forwarding your documents to finance companies which has no sense for me. If they wish, they are welcome to Algeria.
They can't answer me when I ask why I should pay for a service which I had not bought.
3) Far away from basic technologies:
Imagine a hosting company which has been pronounced as "the best by some other commentors" has no credit card payment gateway
4) Configuration of your service is an illusion:
I have been over 15years in the market and I am able to manage some performance tests after buying a vps or a dedié and I did the same process after check out the shopping cart in Netcup's page. The weird thing is that what they promise and what you get are not the same. When you check out the memory of dedié, it shows 64GB ram in command prompt but if you wish to check the real ram performance, it was not going above 40% of guaranteed ram in a virgin server.
Dedicated traffic premised by Netcup was 1gbps but it was around 300Mbps during the test. Seems like dedicated server is not a real dedicated server and we had noisy neighbors.
If I were you, I would have been keep away from Netcup. Because I do it that way.

TLDR; Pick someone else as your hosting provider and heed all the other negative reviews about this organisation. Learn from my own mistake and thoroughly do your homework. If what they offer sounds too good to be true, you can bet that it is. Avoid doing business with netcup under any circumstances, no exceptions.

netcup came to me recommended as a company with excellent hosting and service. They have massively fallen short of that promise and have been an absolute nightmare to deal with. If you plan to chose them for your hosting needs, be prepared to spend an inordinate amount of time fighting about spurious charges, quibbling over semantics and waiting for delayed responses from their support team. That said, expect correspondence from them when you owe them money: your head will absolutely spin with the speed with which their email hits your inbox!

Hosting-wise the performance of their servers is reasonable but not the best that I've seen. For the most part, I've found it to be reliable although I've had lots of unresolved issues with other ISPs blocking mail originating from the netcup hosted server IP address range. And despite assurances to the contrary, this issue has never been adequately resolved by the netcup team, which is a nuisance and paints you in a very unprofessional light when you are a reseller and your own customers cannot send mail without it bouncing. If you need reliable email, route your email through a third-party.

Generally speaking, their service team is friendly although the only avenue available for support is email or calling their German support number. They do not offer a ticketing system like many of their competitors do, and email threads get very colvoluted with multiple agents providing support in varying levels of comprehendible English.

Expect most of their documentation to hit your desk in German - despite repeated requests to provide it in English. For the most part, however, Google Translate is your friend if you're prepared to put up with running everything through a translation service.

One of the biggest and most costly annoyances - and perhaps where they make up their margins on their low-cost hosting - is that payments can only be effected via a direct bank transfer or via Paypal. The former almost always results in some or other issue for which you will be charged. If you challenge or otherwise do not pay the unfair charges, expect threats of being handed over to one or collection agency. Based on other reviews, I have no doubt that they make good on their threats.

One final point and it's not something that I've ever had to deal with for any other hosting service I've purchased: if you plan to cancel any of their hosting services, be prepared to pay for a further two months. Netcup requires one full month notice and no matter how you spin this, it works out to two additional payments.

A company with very bad customer service. Hard to understand the layout and not very beginner/advanced friendly. Not really trusting the storage system with WordPress, it seems to be filled multiplied by three. Very focused on getting the contract and the money and forgetting about you afterwards. Don't let yourself be trapped by the great support before signing the contract, it vanishes afterwards. I would never recommend this hosting platform to anyone. Which is sad because the price would have been great.

They started to have critical IPv6 issues, I had to cancel my all paid in advance services because of this but unfortunately, they took it in a very bad way by suspending all my services and indeed claiming for suspensions fees.

I agree with other posts, this company follows very unethically/intimidation practices like sending debt collectors for something that indeed is already paid.

These guys will send a collection dept without communicating with you first! I overpaid the invoice to these suckers and they ended up NOT deducting it!!!
DON'T DO BUSINESS WITH THEM!

DO NOT DEAL WITH THIS COMPANY

Had a VPS with them, it's crazy it's 2020 and they can't auto charge your card or Paypal account like any other hosting company.

Had forgetten to pay this months invoice (June 2020) and 18 days after sending the invoice I had a call with the debt collector call me.

Tried to call Netcup and the woman just hung up when I asked her if we owed them any money.

AVOID

Please check the other reviews too as they had the same issues! Very, very nasty company! I canceled the contract but they never sent out a confirmation (on purpose?). At the end of the quarter the just mailed me the next invoice and told me that they're going to enforce it if I don't pay. If you ask me not a very sustainable business model.
