There have been so many accusations and counter-accusations on the subject matter of fraud so many players have come out with evidence of scams against some sites while the operator of those sites come up with counter-accusations that players violated their T&C.
I think it will be proper if an online accredited court is set up to judge such cases, rather than leaving them uncensored.
I remember there are forums to take care of such fraud in forex industry. Here in this forum as well people will try to provide you a resolution if a casino's representative is available here.
