have you contacted them through email or on their Twitter account? their representative was active earlier but didn't see your post since they logged out hours before you made your complaint post. I sent them a PM just in case they miss your complaint when they go online in the forum again.
I wrote to the e-mail address, but got no reply.
you could try and wait for a few more days, sometimes casinos take days(not that I approve of it) to reply to an issue. that being said, their claim of up to 900% cashback and their refund policy, when a gambler is not satisfied with the gambling site, is a little too good to be true which usually means it should be avoided. anyway, I still do hope they pay you your winnings.
I hope for something good, too. But already hopes are dying, it's been two days, and still no payment.
