Give them a different contact name. I was recently almost banned and I made a new account just in case they went nuts on me. As others have said get a new everything and then make up some new name as the company contact. Because all they have to do is search their db for your name and kill the account.
I did that too, made up some name as a contact.
I'm gonna register a new company and try sign up again on a new machine. Will update here how it went.
