Hung up as soon as he started talking about the amazing vacation I've been pre-selected to win.

Hi this is Jeff from Customer service ...... We have a great offer for you. Discount trip to Orlando including midnight rides on a leaky boat across the alligator lagoon.  The whole thing is a recorded blabber made to sound like a real person.  I called back the number preceded by *67 to block my caller ID.  The answering message said - the survey you are responding to has concluded.  This must be a shared scammer number. Don't answer. I blocked it immediately
