It's service that I used before I got virgin when we had BT and dropped 99% of automated/unwanted callers. It'll take a few months to filter through to the lists.
I've just done it again on my new VM phone as I keep getting auto messages but as there is a limited amount of numbers going around I presume someone else had it before me. Too ealy to tell if TPS has had any effect yet as I only did it last week.
