Next day I tried to spin the slots but I found my account blocked. After KYC verification I was declared that I was allegedly a cheater and my modest win 9306,73$ would be seized. I was brought back my deposit and said that I created multi accounts though I do exactly remember that I have never signed in this casino before.
Casino 500 accepts bets but it is not well-off to pay out the wins.
So you were betting while being drunk and you don't clearly remember what happened? Is this a betting strategy or something?
It seems to me that this is yet another example of shady/sketchy behavior by the casino. This is weird, because Casino 500 has a fairly decent amount of positive reviews on Trustpilot, but Trustpilot reviews can be faked, so I don't know whether this casino is legit or not.
At least you got your deposit back, which probably means that the casino isn't trying to directly scam you and steal your money.
I can't discuss the casino's claim about you having multiple accounts. Maybe you are lying or maybe the casino is lying. I can't tell who is right and who is wrong here.
