Nothing is illegal in the mostly unregulated world of Internet gambling. Based on only your side of this I'd call it fraud. One of the purposes of my site is to advertise only reputable casinos so that you can find a safe place to play online without running into this kind of problem. If you click an advertiser's banner on my site, open an account with them, have problems, and are unable to resolve them with the casino, then I'll help arbitrate. But I'm almost never called on to help because I pick only reputable casinos in the first place and players by and large don't have problems there. I know this doesn't help for your current situation but it may help for next time, and it can certainly help anyone reading this who needs help picking an online casino in the future. Since online gaming is mostly unregulated it's extra important to pick a reputable casino in the first place. Good luck with your dispute.
