Would you mind sharing the screenshot backing up your claims? You can blur or cut out any personal/sensitive information that is in the email conversation between you and your bank.

Also, have you asked bc.game support directly about this? This seems to be a serious situation, so asking their support would be the first move to make. And yes, I know how horrible their customer support is, but it wouldn't hurt to try.

Anyway, we can wait for holydarkness, but I wouldn't be surprised if he asked for evidence first before proceeding on making contact with bc.game.
