Yes, I used vpn. But now in Russia all foreign bookmakers are blocked. While I was making deposits, there were no problems. While I was losing everything was fine. But as soon as I won a little and asked for a payout, my account was blocked.
This is where the main problem is came from, they're not allow their users to play using VPN and of course any licensed casinos right now are ban Russian citizens. I don't know really sure if Playbetr was ban Russian since 2018, maybe it was a mistake by them.
They can ban the player but at least they should return the fund deposits. They can waive the winning amount since we can consider that the winnings is invalid. It is a robbery when the fund of a player got banned because of certain circumstances and is not the result of player exploiting the casino for his own benefits.
The fault is on your side since you're careless to not read the terms of service and suddenly deposit to their casino, remember any site usually updated their terms of services every year especially when Russia get sanctioned.
They had the account blocked and then unblocked, so what do you think the player will thinkg? Of course he thinks that he is free to play on the casino. Regardless, I think the original fund deposits should be returned if it accumulate winnings. But if the deposit amount is losts then there is no need for the reimbursement of fund.
