Has been calling regularly for over two years, never leaves a message. Call terminates if you answer. If you try to call back there is no answer, just a message saying voicemail has not been set up. Reverse look up shows a person by the call ID name at an apartment building, no unit # of course. Bell's suggestion is to either get their block service for $6.95/month or do a call trace for the next time they call and to contact police.
