This market is full of scams. I was scammed two times while making the first deposit - card details stolen, and after a week, 0$ in my bank account.
I'd recommend being careful with them and doing some research before choosing where to play.
Really can you mentioned the casino that scammed you while making your deposits as you claim, we use to warn against scam casinos here in the gambling discussion board and we already have some notable scam casinos such as 1xbits and the rest of the other bursted casinos that have scammed forum members in the past and I urge you to mention the name of the casino so that you can help other forum members to avoid becoming a victim of such scam casino.
Agree with you on the need to be careful in chosing our gambling sites, we have a lot of them already well established casinos that you can play on and have rest of mind and security of your money, and among the cryptocurrency casinos, you can put in for stake which is currently the largest online crypto casinos.
