Big problem with CDPoker. Please help if you know anything.

[Zygote]

I found this site offering a 120% bonus up to 700$ from some affiliate site and while trying to deposit, a online help screen came up with a guy trying to help me deposit. I attempted several times, with no success, using my credit card. the guy helping me couldn't figure out why and my credit card company said that they weren't even recieving a transaction. Suddenly, my credit company says that they can see i have been charged, but the guy helping me stops talking to me. No one answers there phones. I have no money credited to my account and I never completed a successfull transaction with the site. I am sure, according to my credit card company, that they were the one's who charged it. What do i do?
