My thoughts exactly. I have an impression that what Game-Protect is doing when he is "helping" someone to get their money back, is spamming the casino with complaints, threats etc., and in the end some of them give up and pay.

We have a lot of such "services" where I live. They propose their clients "to resolve the issue" for a small percentage in return. But what their clients don't realize is that they could resolve the issue by themselves just as well, without  the need to pay anything to anyone.
