Not sure why this site took even your deposit amount in which most casinos returns the amount and will blocked you permanently ,this same case happens in those accused being scammer.
hope that there will be lights as I am not familiar with this site and wondering where did you happen to meet them?
that does not stand that they are proven scammers , anyway like what said about try askgamblers and casino.guru for other option of them clearing your case .
though there is no assurance that you can ever take your funds as this is only the site can bring you.
