Contrary to most other clouds, Hetzner has a DE & EN support phone number: https://www.hetzner.com/support-center

Did you call them? What did they tell you on the phone?

I've been with them since 2004 with currently 100+ servers and cloud instances among my companies. Yes, they employ one trigger-happy young sysadmin, who can be quite stubborn, too. But in all the years, they never took any action completely without reason. Like we might disagree about the weight of my mistake, but there always was one.

If I had to guess, you were working on Crypto or used torrents. They insta-ban for some protocols. Also, if you connect to too many unroutable IPs, they will create an "abuse" case and disconnect the offending IP from their network.
