Huge Problems with HostSlayer.com !

1) I have been unable to access the Control Panel for almost 1 year.
2) I cannot remove my credit card from my account

Support DOES NOT RESPOND. Generally.

Can’t insert pictures here, sorry:

Tickets just close in a few days! No answer:

The Complaints Department also does not respond:

What should I do? Where can I go / complain?

Thanks.
