Ongoing calls day and night from this number. The person hangs up when the phone is picked up.

i got a phone call from this number and it was a telemarketer asking if i was interested in making extra money from home. I politely said that I had been burned by these things before and that I was not interested. i waited a moment for the normal "ok thank you for your time" instead I heard the man on the other end of the phone say in an agresive tone " fine then you snooty B***H" caught of guard by this I responded "excuse me" then i heard the man say "You heard me you B***H" then he hung up. The caller ID on my phone said that is was from Phoenix AZ. when I tried to cal back it said that the number was not in service.
