Before a gambling site could ban your account and restrict you from gambling then there is a reason why such actions was carried out. I would want to know; did you by any means uses VPN to create account on the site or do you have multiple accounts on that gambling site? This are the only thing that casinos highly frown upon and also irregular betting, when they discovered irregular gambling and pattern on their gambling site they would have no options than to strictly ban you from their site.
Last I knew Gamdom allowed VPN users.
Had never used the site before to gamble, since most of the site do restricts the use of VPN, but however it's important for them to speak out so op could know the reason why he was blocked from having access to the site and not making use of the withdrawal option. I have just checked their
official ANN and it seems that their representative is not that active anymore also their thread is active, I think the last person who posted there was around January last year, this is to show that their activities over here is extremely poor and may not likely respond to you.
