I had Dodge doing that for a couple of months trying to get me to buy an extended warranty for my Dakota. They kept switching phone numbers every time I would block one. I finally had enough and called their HQ and filed a complaint and let them know that while I will never be pressured or harassed into buying the extended warranty that I might very well get pissed off enough to never again buy any Dodge or Chrysler products. It seems to have worked for the last 5 days.
I just called the do not call registry @ 1 (888) 382-1222 and now have my cell phone on the do not call list. This thread lit a fire under my ass to get that done. Thanks for the reminder Parts.
