Complaint Review: Caribbean cruise line

On March 23rd I contacted a customer service line for PIC induction cookware. After talking to a representative and correcting an order she informed me that I would recieve a 'gift' for all the trouble, she then forwarded the call to Barbara Cooper with Caribbean Cruise lines offering me an all expense cruise to the Bahamas. While talking I was asked for my credit/ debit card multiple times and told that All cruise lines do this. After giving my information (which I fully regret) I'm transferred to a man who then tells me that $118 plus $624 would be charged to my card. That was the first time throughout the entire call that I was notified that I would be paying out of pocket. The representative then ensured me the cruise wasnt a scam and asked multiple times to put %1 of trust into him. Long story short, the next representative told me that I could get a complete refund within 3 days of the call. I tried calling the number they'd given me then realized it was a fake number when it didnt go through. I'm horrified I won't be able to contact them before the 3 days are up and that they'll keep my money.
