Any chance you can share screenshots of the conversation you've had with their support, just to make sure you can back up your claims?

Just curious, is the $250 balance on your account a money you deposited or because of their affiliate program?

I will try and PM their representative to address your issue, they might be able to give more detailed information as to why your account got banned. Maybe you should also provide the username you use on their casino or your account's UID to make it easier for them to identify which user is having an issue with them.
