Telemarketer stole my Phone number.   The guy kept calling about “windows”, I knew it was a scam.  He was so rude to me because I wouldn't buy from him.  I finally got mad and told him to leave me alone in so many words.  He said he going to make my life hell and from there he started to used my phone number to call other people.  I don’t know how they do it.  They can just take your phone number and start using it.  I called the phone company and the FBI.  I filed charges but they are telling me the person is out of the US and nothing they can do.    I have canceled my phone number.    This is what really happen.   You would think the phone company would have a little more control over their own system and numbers.   I had that phone number for OVER 25 YEARS, now it’s in the hands some a-hole telemarketer.
