FireKirin complaint: Thieves stole my winnings after taking ALOT of my money for me to win them

I have been playing with the same casino through Facebook messenger and Facebook for over two years now . I’ve won a bit but I have def lost alot more than I’ve won and yesterday after making 4 deposits with them totally close to 200 bucks I finally won 300 dollars and when I tried it cashout like I always do when I win with no problems they said my account was suspended due to suspicious activity which I don’t even see how that is possible I pay them the money they load the money on my fire Kirin account I play the money and either I win or I don’t how is it even POSSIBLE to do anything suspicious ??? Then they blocked me and closed thier account on cashapp and Venmo I had used to deposit with them I still have the records if the money I sent them but I can’t request a refund or anything because they have closed the accounts .
