The caller is a SCAM company called Grand Carribean Cruise Line or something to that extent. They try to sucker you into a cruise deal. Read the blogs about them; they do whatever they can to get your credit card # (telling you they won't charge it, they just need it to make your reservation which you can use anytime in the next 18 months). Once they have your card number they charge hundreds of dollars without telling you. THIEVES!!!!! big scam, AVOID.
