Scam, calls you a lier and wants insurance info.  Person speaking is NOT American nor people in background.  try to call back and auto recording says number is not in service.

I keep telling these people to stop calling me and they refuse to listen and hang up on me.  Plus they just continue to call me.  Tried to call number back and recording says number is not in service.  They are trying to sell me auto warrenty on my car.

Called me yesterday at 3:41pm. I didn't answer. Here's a good tip though: if they call again, get an air horn and use it in the mic. Whistles also work. Or any loud noise for that matter.

Noooo!  You are giving some poor advise that just makes things worse.  All that does is piss them off and then they spoof your phone number on peoples caller ID and you start getting hundreds of continuous calls from people cussing who think you are the unwanted caller.  It has happened to others. Best hang up or don't answer.
