Casino.com is Scam

I joined casino.com and received my no deposit bonus. I was lucky and won and kept playing until all bonus wagering was done. I believe I was playing money that belonged to me as I had done all I was asked within wagering requirements unfortunately not. I first tried to withdraw 1000 that I won but days later still pending. I deposited 20 and again tried to withdraw my winnings but no joy. I was then asked to provide identification which I done immediately but still withdrawal not released. I then cancelled withdrawal and was playing money until I got bored and finically tried to withdraw 300 left. I’ve now been blocked from account and none of my emails are being returned. I’m a frequent gambler and have accounts with all the big companies like betfred jackpotjoy and William hill. Never had any problems like this ever!!!
