Caribbean Cruise Line 2011getaway.com, "free" cruise palm beach, Florida

Recieved "boarding pass" offer in the mail for free cruise (special offer). I stupidly gave my credit card number over the phone and my account was charged $250.00. My wife called them up screaming and they told her it was too late because I willingly over a recorded tape gave my card info to them. After I gave my card info, the asked for the CVS number on the back I ended up hanging up because I realized something was fishy. They ran my card anyway. I am fighting to get a refund. They told my wife it will take 3-5 business days but i'm doubting I will receive it back. TOTAL SCAM. People shouldn't be legally allowed to get away with such a thing after it occuring just once.
