TRY THIS
I registered with them a couple of months ago and it's brilliant. Occasionally you do get teh odd call coming through. But I interrupt and say (very politely) that I'm with the TPS and they tell me they'll take me off their lists.
Absolutely brilliant.
I still get the odd recorded message, but the number of these has dropped dramatically (now one a fortnight rather than one a day).
Laters,
