I cannot imagine this man. Why would a gambler play at a casino that doesn't allow players from his country? OP dug his own grave, in my opinion. If the support said that he should not have any problem, this was a trap for OP. They work for the casino, and I think they also want players to make mistakes and lose money. It seems OP violated the rules, and I don't see much hope here.

I am not sure if holydarkness would be able to do anything. But since he already said he would check it with his contact, let's see if we can get some positive news. I thought BC game has a dedicated platform for USA players.
