However, if you did something wrong then they are going to keep that money and in order to be able to see that, they have to halt the actions of that account first, check it, and figure out what's wrong, and they will tell the customer what was the abuse they did and just keep the money. That's how it is in every casino.
When they find something suspicious in your account they will block it so the first thing is you can't withdraw the amount from your account because it's the first step the scammers will do after cheating.Then they investigate the matter and if found you on the right side after all the verification and you can also withdraw after that.
This is what we called standard operating procedure or SOP. When there is abnormalities on the account, the first thing the casino will do is to prevent losses thus withdrawal is suspended to the point of account suspension. Next is validating their suspicion, if they are sure that a player violated the rule it is outright banned without any documentation needed from the player but if they suspect the player is playing from a restricted country, multi-accounting, then they will ask for documents to verify their claim. If there is no problem then the casino will return our account to normal state. The problem with a cheater is that they keep on insisting that they don't do wrong while not providing the needed documents required by the casino which prolong the case.
