I am guessing that if it was deleted in under 24 hours, then you registered and put in fake client information. We have 0 tolerance for that and remove free servers on the spot now if you use fake/false information. If you want to send me a PM I can look up your account and see what happened.
People need to realize that if you register with fake information, we will just cancel your server without warning. If you keep signing up for servers and don't fix your contact info, we will just close the account.
