My advice and experience is don't use Netcup. They are abysmal at customer service. I once registered a domain with them, and hadn't even paid, but then couldn't get my account deleted at all. Even multiple e-mails did not help and they insisted on keeping my data until half a year later or so. They absolutely behaved like complete holes, and I will never trust them again with anything. I don't know what they do with user data. Maybe they systems are just so terrible, that it is a huge effort for them to go and comply with GDPR deletion request and then they just don't do it.

Also their web interface doesn't allow you to delete your domain, even if you have not paid yet. So anyone could come and make some account and register a domain, but then not pay and they wouldn't remove it from their systems. The feel of their website is very antiquated and due to not being able to delete your domains, feels buggy.

I’m not exactly a user with advanced needs, but I have a server with netcup and never had issues. I also know a couple of people who never had any issues with them. I know them as cheap and solid, never even heard of a bad experience I think.

Bummer they failed so hard at your deletion request.

I am using Netcup over the course of 20 years now and tbh never had any problems. Their customer service is very friendly and they responded quickly to me every time. Sorry to hear your story, but I think this is an exception? I had domains there too, but moved away because of functionality. But my main hoster is Hetzner for a decade now. But because of vendor lock out, I am glad to have Netcup too, especially if you consider the price!
