So, where is the provable scam?
You say you lost your money to the casino. You know who else does, maybe 90% or more of casino players. Of course the RTP is not as advertised, show me one site where it is.
Casino games are evil, especially "original" games on sites that have them. When I play them I NEVER have the advertised RTP, never. Sure people always say it's just a small sample size but when every single session starts with countless losses there will never be a big sample size because the money is gone WAY before you can even have made many bets.

Still no reason to make a scam accusation, I never did, countless others never did, because that's just how it is. When we lose money it's gone.
You said you complained a lot about the RTP in the chat support. So if you felt something was fishy, why the hell didn't you just stop playing there?? You can't excuse it with gambling addiction, because you could have simply went to a different casino if you felt this casino is cheating you. At a new place you can "keep living the dream".

Also, them "making you an addict" is not a reason for an accusation like this. For this you should take this situation in your own hands and seek help. Gambling addiction is the fastest grown addiction at the moment, for good reason. SO there is a lot of help you can find if you really want to.
Always see gambling as entertainment, not as a way to make money quick, it just doesn't happen, at least not for the vast majority of players.
