Wow,pretty common drama if you ask me.
Lots of crypto casinos have those fake "hooks" like no-deposit-free-bonuses and other shit like this.
When you signup just to claim that "free bonus",they come up with some hidden rules to claim that bonus that you didn't comply with and there you go.You get nothing that was promised.
I'm sorry about you,but that story with the customer support made me laugh.How can those people be such f**king liars?
