Hi Clueless, that is funny. I didn't answer the call but in the past when I did, it was a recording, as you said, and they wanted to extend my warranty. I also get unsolicited snail mail for the same thing. Considering that I have a 1994 Jeep and have never had a warranty, I just laugh at them. No telling for the lack of brains. :)
Figured it was a spammer, didn't answer it. Called it back out of curiosity and all it aid was: "Please press 1 to be added to the Do Not Call list of the party that called you." No other option. No one comes on the line. No way to leave a message or to even know whom the party was that called. Confirmed: Spammer
