Ok my mother keeps on getting calls with unkown caller on the caller id of course you can't *69 them because of that. The phone calls are driving her crazy, someone calls and ether hangs up or will stay on the line until someone answers.She can't get any sleep because of this and she gets about 40 calls a night. (annoying as hell)

My question is there away to call that person, or take off the unkown caller so I can *69 them. Even if there is a way to get the phone number I could at least call the phone company and have that person arrested. If any one knows of away they could help me out alot.
