If so, you have done the pre-test. Unfortunately, some casinos scam players only if they see the amount is big enough. Of course, I cannot tell if they are scamming you or not because we haven't heard the story from their side. So, it won't be appropriate to call them scammers. It would be better if they came to this thread and shared their point of view regarding this case. I have heard their rating on Casino guru is not good. So, I don't know if opening a complain on Casino guru will help or not. But, keep us updated about your case.
