I got confused at this point. From what I understood, due to some bug, you were being able to register on tournaments for free. You manage to win one, and lose the other, so why was your balance the same? Shouldn't you have more money on your account since you registered for two tournaments without paying, and you actually won one?

Also did they give you any reason for why they have locked your account? I mean, apparently you tried to exploit a bug, instead of letting them know right away, so even if it was their fault, I guess they had good reason to lock your account in order to try to understand what happened.
