They called and would not say who they are.

they called and said I won a trip but told me they want 500.00 first.

The told me it was a 287$ registration fee for an amazing trip. Sponsored by Disney vacations.  They had my address wrong and said I was registered with Visa - which I'm not.  I hung up and called the number back and they greeted me by name and gave me the same spiel.  They would not identify who they were until without CC information.  I told them that I would be an idiot to give them my CC information without getting their information first.  Talked circles etc.
