I have been registered with the TPS for years and it seems pretty useless to me. There was an improvement initially but the calls soon started coming again, and as time has gone on it just gets worse and worse. I get at least one call every day - sometimes as many as four.

It's the same as putting a sign on your front door saying NO COLD CALLERS, LEAFLETS,RELIGIOUS GROUPS, SALESMEN  etc. They still knock and when you point out the sign to them they say " Oh, ha ha, that doesn't apply to us".
