What scam is this?

.only to answer and it be someone trying to sell you an extended warranty on a car or to let you know that you can get out of your financial student loan debt!

Now that make sense as I continue to get calls about student loans that I hang up on right away. I answer my phone all the time no matter what. Maybe its time I stop that practice. Also I guess I shouldnt reply back to those inquires of is your car still for sale!
And I thought i was being the smart *** by replying back!
Thanks for all the reply's. Hope others learns from this question!
