dont take chances with these phone stalkers. call the police. its too easy for killers and rapists like these to get your address, your kids school address, your phone number, etc. put these criminals in jail where they belong.
Same thing as Mr. Paul that posted prior to myself and Nick. They've been calling for a few months. Can't figure out how to stop them from calling because they will call from alternate numbers sometimes but with the same message upon returning the call.
The reason they keep calling? You call them back. That tells them yours is a valid number (their robo-dialer calls randomly; when someone answers or calls back they know they have a live wire.) Don't answer; never call back.
