I just got a call from this number too. The area code is from LA or downtown Hollywood. When I called it back, a recording came on and said it's a non-working number. How weird is that?
This is one of a series of fake Caller-ID phone numbers from a company that's pretending to sell warranty extensions for your car. Don't give them any of your private information because they're con artists. They refuse to give the name of the company, using something vague like warranty services.
