This is sad to hear. I read a lot (and I mean a lot) of reviews before playing online and I have mostly only read favorable reviews of the casino. Even the harsh critics on reddit were semi impressed with redemption speed. Did you complete all the checks they do and send all your information in?
I will add, on the flip side, I have played here for several weeks and made a good few hundred dollar withdrawals without issue. I am also a fan of playing at jackpot and zula where I have also had no issue with redeeming winnings, albeit small ones.
