Worldwinner.com online gaming site keeps taking my money! online caseno rip-off

I deposited some money into my worldwinner.com account but it never allowed me to play any games. I sent several emails to them and got the same thing "the bank reported illegal use of your account". I phoned my bank and they said no such thing was ever said.

Well, worldwinner.com closed my account with them and now wont give me back my deposit. They claim the only way to deal with it is to fax them the front and back of my credit card (as if I'm that dumb)! I have emailed them at least 20 times telling them I want my money back and if they closed my account they should have no problem doing it. Like earlier, I keep getting the same email about problems with my bank.

I have asked them for a phone number but they don't seem to want to provide me with one. Anyone know how to get ahold of them or who I can report them to? Watch out, they ripped me off (too bad too because I enjoyed playing my games through their site)!!!
