Have rec'd multiple calls from this number since the summer began, all to my cell.  No one is ever there; no message ever left.  Ridiculous dead air - WTF!

And.....when you try to call them back.....just to give them a piece of your mind....you get a recording that says "you have reached a number that has been disconnected or is no longer is service, if you feel......"

Just remembered new update includes ability to BLOCK calls....so, done!
