This is a message board for discussing spam and scam phone calls. Your calls are not coming from here. Your pest will not see your request.
If the calls continue get a call blocker. For a smart phone a call blocker is an app. For a land line a call blocker is an electronic device you plug into the phone line between the line and the wall. For a simple cell phone ask your carrier.
Actually, I read this to mean to add this number to your blocked numbers on your own cell phone or to call your phone company and request it be blocked. Why do you have to be rude and condescending to someone who's trying to help everyone?
