I am trying to understand what they mean by hundreds of games. It is completely fair if there are hundreds of rolls in slot games because it's not impossible to play hundreds of rolls in slots. But that is unbelievable if they mean hundreds of different games (slots). If the casino accuses this player of playing hundreds of games in 20 minutes, that is only possible if they use some automated process in multiple tabs. I don't see any other possible ways.

The casino rep should understand that when a player newly registers at a casino, it is very much possible to request a withdrawal faster because players want to test if the casino is legit or not. There is no reason for a player to play the whole day, and the casino does not pay at the end of the day. I also check casinos by making a withdrawal request to check their withdrawal process. This is not unusual.
