How long has it been since your account being locked? If I understand things correctly, your
past case with 500casino was a simple matter of waiting while your account being investigated, is it perhaps a case with similar nature?
500casino approved withdraw only after casino guru accepted complaint. Now casino guru are absolutely unfair site. betsofa.com scammed me with 15000 euro, but casino guru closed complaint.
At this moment only vavada.com and bspin.io make withdraws without dirty unfair tricks. this is 2024 year reality.
Maybe you are the one having a problem with your gameplay since you encountered many issue from different casino which means you are doing something that violates the casino ToS for your own game.
I’m not sure what method you are using but having a lose on casino doesn’t that you are playing fairly since arbitrage bets is still possible even on casino games especially live games while you are using casino bonuses.
