Number calls and no one answers

they called and i didn't say anything to see if it was a recordind and I heard nothing so I hung up, i called back and it said that it was disconnedted or no longer in service, so probably some scammer

SOMEONE CALLS ME AROUND 1-2 AM EVERY MORNING AN I'M SICK OF IT

got a call from this one, and another one there in Sloan, Iowa 712-429-0258.  I answered the first one, it hung up when I answered.  This number I didn't answer.  After the second call I tried calling both numbers back, both give a recording saying it's been disconnected or a non-working number.
