This is a link to the telephone Preference Service (I assume you are in the UK) They are very good.Just contact them. Best not put phone calls on here.
I got a call from some kid cussing a blue streak on my answering machine. I called them back and some lady answered and she said no one call your home from here. I told her "how do you think I got your number? It was on my caller ID." She then said I know who it was i'll take care of it and I never got another call.
Prank calls are only entertaining for immature kids its old prank calls are out of its timeline
