Come on man Buff88, do the only right thing here and give this user GekkeBelg access to his account back and let him withdraw the remaining balance. This is how all bookmakers/casinos do it when they exclude certain countries.
I did some research and your parent compact XB Systems is listed on the Vienna and Munich stock exchanges and planning to join the Nasdaq soon. Do you really want to enter that phase with a scam reputation?
Do the right thing here and the whole outlook will change and all will be back to normal here. Im sure GekkeBelg is even prepared to delete all negative previous posts if you ask him.
