If you follow the bets / rolls, streaks and guide yourself from a probabily fair code check you will be able to verify your bets.
Try that in first place before assuming some Cassino is rigid / has fixed bets.
When it comes down to losing money in casino everyone thinks that the casino is rigged and they wont be able to win back their money. While mabye a few minutes back they were the same people who trusted that casino with all their money.
Its human nature to be self-centered and thus this happens with every liberty seeking person out there. They know that the casino's bets are provably fair but will continue harassing mods and support team with complaints which ultimately have zero effect.
