I don't think that you are unaware that casinos have the right to ask for clarifications if they suspect your account. Any casino that offers total no KYC will go bankrupt because cheaters will take of them. If you are sure you have not violated any provisions of the TOS, I suggest you go through the process, and hopefully, your account will be unfrozen if you are clean.

If you are not satisfied with the outcome, there is a section called scam accusation that you can seek redress.
