Who called from 8647080202

This company has called me 6-7 times now and I have politely and now rudely asked for them to stop calling me.  Guess what?  They are still calling.
They want to sell auto insurance/warranty service on a vehicle I purchased under a year ago.
Buyer BEWARE!

I answered and it sounded like a recording of a woman saying "hello?" Over and over but she wouldn't respond to me. I tried calling back and it says the number is disconnected.

Has called me twice in the last two days.  Does not leave a message. I have not answered or tried to call the number back.

Just called.  Sounded like a very good robo call.  Robo woman asked if I had time to answer a few questions about my Auto insurance and when I stated NO she continued like I had answered YES.  I then Hung up.

This number has called me numerous times. I've answered once and nobody said anything. I think this is a scam
