I try to chat support online but their reason my account banned because fraud with bonus, I never joining any bonus program and only active with gambling on sport side, how come 2,3k doge coin received from bonus, here my fund and my account still banned until right now
I hope you are not Russian 
. Everywhere poor souls are in trouble - Why would they do that? Did you contact them again for the support I am unable to digest that you have keep so much amount at one place. Many a times in different forums member have mentioned not to keep all the money in soft wallets. I can pray that you get your money. And when you get it - don't let it stay there! This issue was raised last year in December and we had enough discussion on it. We haven't heard from the OP if the case was resolved or still unresolved but it seems that this case is still not resolved.
By the way, since you asked if OP was an Russian, this issue occurred before the war and has no link to it. Also i don't think that stake is blocking Russians users ? Are they ?
