not a real number, - car warranty scam

Caller Claimed to be from the National Automobile Division, said he was on a recorded line. Claimed I had not sent back my automobile warranty paperwork ect. ect. told me not to drive and that I was going to be canceled. SCAM, SCAM, SCAM!

Someone from this number called and I work for a DOCTOR. He asked me how many miles were on my car, and I told him if it was that important he would have the Dr.'s cell phone number !! Then he was was rude to tell me he was a Neurosurgeon for 16 years, and was going to report me for being rude. Um Im his nurse you don't call and try to scam people and if he did any type of Neurosurgery that is really really scary.

They called. Answering machine picked up. They hung up without leaving a message.  I did not call them back.

I receive calls from this number a at least 1 or 2 other numbers that also show on caller id as NAD  (National Auto Division). I answered one time and got someone who started yelling at me telling me that no my number would not be removed from their call list. Now if I answer there is no body on the other end and it hangs up on me . I'm getting really sick of this!!  It's several calls every single day!
