I apologize for the frustration you've been having with this.
First, your casino account is still open--I'm honestly not certain why anyone would have told you differently.
Regarding your withdrawal, there are a couple bits to be discussed. The first part is that there was a bonus used to build up your funds ($150.00 PLAYMORE300 (1 of 999)(30 free spins)). All bonuses are non-withdrawable and therefore will be removed from your total withdrawal.
Next, there was a $50 reversal made on your credit card (charge back). This issue was already discussed with you back in April. In order to resolve the charge back issue, the $50 will be deducted from your withdrawal along with a $75 fee which is imposed on the casino by the processor.
With all this, $275 will be removed from your total withdrawal amount ($150 bonus, $50 for the charge back amount and $75 for the charge back fee), leaving a net withdrawal amount of $225.
In order for me to have your withdrawal sorted, I'll need to receive your preferred method of payment. I've just sent you an email regarding this--as soon as I have your reply, I'll request your payment be sorted.
All the best,
