BetBeast Sposrtsbook - Confiscation of winnings and part of the deposit PLN 6365

Dear Askgamblers, BetBeast has confiscated my winnings and part of my deposit. I bet on the Swedish women's volleyball league match between Engelholms and Lindesberg. I bet my entire deposit of 3,000 PLN on this match. I won the match, later verified my account, and attempted to withdraw the money. I received a notification from them that my withdrawal would be processed as soon as possible. After a week of waiting for the withdrawal, I received an email from them stating that my winnings had been confiscated and my deposit would be refunded. However, the entire amount was not refunded, only a portion of 2,000 PLN, even though I deposited 3,000 PLN. According to the email from BetBeast, the reason for confiscating my winnings is a betting technique related to prohibited activity. I believe I won the money fairly, and my bets did not violate the regulations. This is because my bets were within the limits set by BetBeast for this bet. Dear Askgamblers, please help me recover my money from this bookmaker.
