We accept full blame here. First, we shouldn't have assumed that a deposit couldn't make it to our bank account without also making it to our system. Second, it's taken way too long to credit Giorgos's account after the problem was discovered. We found the deposit in our account last Friday and his account still hasn't been credited. To credit the account, the deposit information will have to be entered into our system manually - the person who needs to do this has been extremely busy, but still that's no excuse.
