it's a scam.
I make withdrawal and they do not pay.....

Avoid using a scam casino because there will be a high possibility you will lose your deposit including all your winnings this is because most of them will allow you to deposit and play but the moment you make a big win and want to withdraw then you will discover that their pour scam, and the first thing their do is to suspend the withdrawal and thereafter banning the accounts.
But then it is good that whenever we share complaints we should share some evidence in other to show the legitimacy of the accusations, but then you will have to move on with your life and only play on reputable casinos only to avoid this kind of issue with withdrawal.
