OP, can you share your wallet address? If you believe that this is a mistake on the part of the casino, please advance your case to any reputed third-party mediator.
sharing his wallet address won't help prove anything, especially if he deposited from an exchange.
as i said in my last post, these cases rarely get solved here on the forum, as most of the time the casino doesn't show what proof they have, they only claim they have it.
if OP still insists that he only has 1 account, he should file a complaint with askgamblers:
