Complaint Review: "Warranty Service Center"

I receive several phone calls per day from "Warranty Service Center" even though my phone is on the do-not-call list. "We have made several attempts to contact you..." and my auto warranty is about to expire. (My car is almost 16 years old.) I can press 1 to talk to a representative or 2 to remove my number from the list. (2 does nothing -- the calls keep coming) When I ask the representative for specific details they hang up on me.
