I never answer this phone number but want it blocked who ever is calling

There is a real person on the other end. i have a whislte that i blow into the phone when i get this call. and i keep it on speaker phone. the last time he called, and i blew the whistle, i clearly heard him say "The hurts" and he hung up. then i called the number back and did he same thing. He said 'Stop" and hung up. There is someone on the other end. may sound like a automation, but it is a real person. or becomes a real person.

Please STOP calling me! !! This is borderline harassment!

Phone rings with this number on the ID but no one is there when I answer.  UGH!

This # called my cell phone a lot and left no messages.  I don't recognize the # so I will not answer it either.
