Casino confiscated my withdrawal of $420

I registered at this casino and uploaded documents for verification. In the chat, I clarified whether the documents were checked, I was told that my account was verified.
I made two deposits through the Skrill payment system. The balance had 420 dollars. I put the means of withdrawal on skrill.
My withdrawal ($ 420) was canceled and the deposits returned.
Wrote: "Unfortunately we do not accept players from Belarus, therefore your withdrawal request has declined and all the winning has been confiscated and your main deposit has been refunded".
I'll tell right away. A person from belarus, who made deposits and withdrawals, recommended this casino to me! if necessary, I will ask him to forward the evidence.
The rules do not say anything about the ban on Belarus.
I saved the rule pages.
The documents confirmed to me.
When registering, Belarus was on the list of countries.

I think it's outrage.
