A couple of weeks ago I signed up to 21casino as well as some other sites in the same group. I made a and availed of the welcome bonus.
I managed to play through my deposit which unfortunately lost. I took a little break and when I went back to play with my bonus I found that my account was locked. I received an email that I was banned from the group for some reason, but that they would reopen the account so that I can finish wagering. However this has never been done.
I am confident there is simply some miscommunication going on. I actually had an agent on live chat tell me he would unlock my accounts "right now", and subsequently that it had been done. The accounts were still locked, he then said it was an IT issue and would be resolved today. I never received a resolution and in fact got the same frustrating emails that the account is still under review. The issue here is the bonuses only get one month before they expire, the wagering is very large on them and I already lost my deposits. Totally unfair!
