Unethical practices

Would rate higher because I actually like fliff and the fact they give u $2 for free and more when u use coins. But im not because I have ran into an issue with them an unethical one! I been betting with them for months maybe 1-2 years now and I have won and lost money with them. I have withdrawn money and deposited over time. But recently they kept denying my withdrawal basically, I had a dispute or chargeback once months ago but eventually paid that off or deposited money to resolve that and even talked to support and they said something like okay that works or whatever. But despite that and after that depositing and betting months after and eventually trying to withdraw my winning they deny the withdrawal bc of that last experience which was resolved. I contacted support and they do nothing just repeated the same script and blame the banking processor they use and say they can’t do anything which is crazy. How can u let someone bet & deposit money but not withdraw makes no sense. I used different withdraw methods and accounts and cards but nothing works.
