I picked up, after saying hello 5 times a man answered asking how I was. Then he started into ''your car may..." I hung up.

No message left on call that came in today on my cell number that they MUST have gotten from Facebook. Nice. :(

They called my private cell phone 6 times.  I consider that harassment.  Online information suggests that this number belongs to a caller who offers to extend your cars warranty.  None of the reports can name the company.  So if you have a fairly new vehicle that has just aged out of the original warranty they may have gotten your information off a list somewhere.   My car fits into that category, but I never do business with telemarketers.  I have read reports about this number, that they ask for vehicle information.  That would be a red flag for me.  Scam alert!
