Slots of Fortune kept winnings

posted on September 9, 2010.

I played at slots of fortune and won 1600.00 . I got down to 1200.00 and tried to cash out. They locked my account and said I had a debt to pay to ewallet express and until that was satisfied it would be locked. ok I paid them and my account was good again. slots of fortune said they will open my account but they are keeping my winnings of 1200.00. Can they do that?
