The questions arise:
1) At which specific date did you first get suspicious?
2) At which specific date did you remove all Felix games?
3) If the official letter from Felix is dated 26th January 2022 yet the OP first deposited and first won funds before that letter was even published, why are you mentioning the Felix vulnerability? At which specific date did you seize the funds owed to the OP?
Do you know that Wazdan and Felix are different providers? Felix was returned to the casino after they confirmed their fault. Wazdan was removed right after OP won his jackpots.
