Well, I guess you're the one who has not read the terms & conditions. In part 3.4 it's clear your money is getting seized, and part 9.4 is also on their decision. My advice is quite simple, If they ignore you (mostly your case is rejected). Moving on, cause the one who makes these problems is your self. If you do not multi-account, then these will never came.

You can also create a thread or case topic in the most popular site reviews like "CASINO GURU" with a good experience from third parties service. They, will stick on the casino side cause you're admitted the case is breached by your self. Term & condition is basically like "law", if you breach it + admitted = dead ends for you.
