change your number, the phone company will log all calls for you, they have a nusance call department you need to contact, they have good advice. they also call the cops for you when they have traced the person
and then find yourself in court for making him deaf, do not use a whistle or anything like that, let the phone company deal with it. you are then on the right side of the law, meating him? what if he has a gun?
Thanks for the comment, however next time actually bother and read the ENTIRE thread before posting anything.
