@Anna1977 It looks like the most probable and logical reason for closure of all your accounts was/is due to the newly implemented country restriction regulation. Yes, even Curacao licensed casinos are not exempted from abiding to this new ruling. So many of us, including myself of course, are now restricted from our once favourite casinos. Hard to swallow, painful to bear, but rules are rules.
So, if anyone checks out a new casino and see that it is restricted, don't even attempt to use a VPN to get access to it - that would only create more problems if and when registration becomes possible.
