"You have been selected by Expedia for three free vacations. You must be 30 years or older and have a valid credit card to qualify". Scam.

The phone number from my call display would be local to my exchange, and there is a significant chance that it was faked.

I pressed 1 and told them I was over 30 (I'm not above lying to a scammer), and was passed to a second person. I then gave the second person a really hard time about violating the Do Not Call list. The person claimed that they had not called me, that I had been forwarded by one of their sponsors. Upon questioning he claimed that his company hired the sponsors. I asked him multiple times why his company was willing to hire companies that engage in criminal activities. He kept dodging the questions but after a time offered to take my phone number and get it taken off the list. I kept pushing the illegality of having been called and did not give my number (because I didn't believe for a second that they intended to honour the removal since we know it is a scam.)

But next time I will know to ask the first person for the name of the company since there is the claim that two different companies involved.
