Go inside your account and take a few screenshots of the transactions. And anything you find important so you have more solid proof. Just incase they suddenly "ban" you for suspicious activity.
I got plenty of screenshots but I dont think they ll change anything. Wallet address and everything are there so obvious. Just stay away from these scammers!
Its good that atleast you see the transactions on blockchain now.
As for the screenshots, its always better to post them ,as at times another casino, might launch a scam report similar to this, and its hard to take sides without proof.
