Oh darn, I just got a call about this as well... It said "press 2" if you want off the calling list and I did that. It said something about a vehicle warranty. first I thought it was a wrong number that someone had given, but now that I see your messages. Oh no! It is scam. I don't even OWN a vehicle!
Wow you are my hero!! :) If I ever talk to them, I might do the same if I feel that moment that I have some balls :D
Or I will just speak my language (my first language is a very small European language, impossible to understand for non-native speakers) and yap away :D
