Here is how this works. They call with a bogus "energy" survey. You answer 3 questions by pressing 1, 2, or 3. They then call you back (another question & answer chatbot) and allege that you are getting free tickets on a repositioning cruise. Then the sting: "you do have a valid credit card, don't you?" Comes down to your "...not fitting the profile..." If you stall, question etc.
