^ You are on the right path so don't go away.
But most commonly the problem is this, there are some casinos you have a problem with when you can manage a considerable profit that comes from the bonus or rewards. Blocking your account or it will take longer the withdrawal because of their excuse is that investigating your account from the massive win. So if you are relying upon these bonuses, you are most likely to experience that case which is very common here and always witnessed here.
Just place a bet and win or lose that is fine, though it is not bad chasing profit from higher RTP gambling casinos but almost of them are full of shit when it comes to withdrawal.
