I'm not sure, but i think the number was spoofed. Yesterday, my parents answered that call because my dad is a member with AAA, & they thought it was really the auto club. They said that his membership was expired & needed to be renewed, (if i recall, he recently did that already) and they wanted his credit card number to start the process or for verification purposes, im not sure. And he said that he never ever EVER used his card for that, he always pay in cash he said, & out of nowhere there attitude changed & they said they were with immigration and threatened to deport them if they don't pay them money. There were U.S. Citizens for crying out loud! So my parents just hung up & that was that.
Best advice i can give, If you get telemarketing calls signup for:
-Do Not Call list,
-Or get a voip phone service like google voice, ooma, skype or vonage (you can block as many numbers as you like)
If you don't get any telemarketing calls:
-DONT put your number on any document, paperwork or a contest (that's one way they get you) unless if its really important & absolutely necessary
-Get your number unlisted
