You ask to be removed from the calling list they call from a different number

I can't be certain, but I may have received a call from this number a couple weeks ago.  The call concerned my expiring mfg warranty on my car and they wanted to provide details on purchasing an extended warranty.  I mentioned I was at work and couldn't devote the time but could I call back.  With that, the caller ended the call -- abruptly.

Answered the phone, but was hung up on. I called the number back and an automated system answered the line.

They say they are calling from "American First".  They robo dial me from different numbers all the time.  They call about three to four times a day.
