I made the mistake of answering, since I'm expecting a call from a local (stranger's) number.  This is a telemarketer selling extended car warranties.  Stubborn caller wanted to give me the pitch no matter what I said, and had a response for all the usual objections.  Didn't catch the name of the company, just "Sarah" like she's my friend!  These guys change numbers like I change underwear.  Told her to remove both my phone & mailing address, but we'll see.
