I have a feeling this may have to do with a company called First Extended Warranty.  Disclaimer, I don't have physical proof, but it seems to fall in line with everything else.  It would seem as if every car dealership in America does their extended warranties through this company, so if you've ever bought a car, that's how they may have gotten your information.  I've been getting a whole lot of spoofed phone numbers either with no messages or messages about extended warranty expirations since mine had expired.  Here is their information: http://www.thewarrantygroup.com/company-overv ... t_extended.html

If First Extended Warranty is the company you got stuck with along with your car, here is their 1-800 number.  Let them know how you feel about their business practices: 1-800-527-3426.
