"Warranty Department" claimed to be Chevrolet (since I own a Chevy, and they probably parse out vehicle registrations) and tried to sell me an extended warranty. Funny, because I already have one for this Chevy. Caller grew belligerent when I instructed him to remove me from their calling list and told them that there's no way that they were GM.
DO NOT give this number your money or information. They called me once last week demanding money for my warranty but would not state who they were with or confirm my dealership.. I would not give them my information and the man became so frustrated with me he said "I do not have time for you" and he hung up. When I spoke to my dealership they said this was definitely a scam and that anyone calling from my dealership would associate themselves with the dealership and would never be this rude. Today I received another phone call (about 1 week later)I spoke to them and advised that I know they are trying to scam me and they need to go ahead and NEVER call me again.. they hung up very fast.
