I used vpn for security, before registration I asked support about the possibility of using vpn, they said that vpn can be used for security, but not to bypass registration from countries that are prohibited from using the site, the site does not prohibit registration and use from my country
What security are you talking about that make you use a VPN on a casino that can ask for your KYC verification at any time they want? It's like trying to lock your door with a thread 
If you are security conscious, then do not sign in to the casino at all.
A VPN will only make you look more suspicious. Try entering any bank when you are wearing a mask and see what will happen, even if you are innocent or just trying to prank
Hi, before registering I asked in the chat if it was possible to use a VPN, they answered that yes. I live in Russia and I do not have direct access to this site. I did not refuse to go through KYC and went through all the stages that they required, but at the moment they do not answer me either in the chat or to my messages by mail. I can not believe that such a large casino does not want to pay out a bet made on the French Championship, this is all very suspicious!
