When they called they knew what make and model car I owned and claimed they represented the insurance coverage for my car (not warranty), and that my coverage was expired. I told them that was a lie and they hung-up on me in mid-sentence.
In fact, my car is still under partial manufacturer warranty. They may be posing as extended warranty coverage but I firmly believe if you gave them any payment info you'd be cleaned out completely and ripped off.
This number called today and left no message, so of course I had to look here for other experiences. Many folks don't know, but some states sell YOUR vehicle information to telemarketers. Thanks Florida for selling mine.
