A problem may arise later, if you do make a win and a withdrawal claim.
No doubt the Live Chat host has said it's okay for you to continue playing, but I wouldn't put my 100% trust on that! Why? Because where withdrawals are concerned, the approval or disapproval decision does not lie in the hands of the Live Chat host, but in the hands of the casino's financial team, which would scrutinise all your game play and bets used. If they see your 100 EUR bet...oh boy...you may face the inevitable rejection, regardless of what the Live Chat host has said to you! The financial team's decision are always the final one!
Aah, the classic max bet accident. You should immediately contact them about it because they will investigate your gaming history and they will find out about the max bet.
