This number was calling me 3 or 4 times per day, for several days, even at 9 PM. I never answered and no messages were left. I just called this number; asked who they were and why they were calling. It's a firm calling for charitable donations on behalf of "police organizations". I must say, fella on the line was very polite, even though I was quite irate and angry with him. Agreed to add my number to their "do not call" (DNC) list. I too am on the normal general DNC list, but that only works for entities selling goods and services for a profit. It does not work for charities. Moral of the story: just call them and get added to their DNC list.
