I have a BT 8500 advanced call blocker house phone. We have moved to a new address and new phone number. All my calls are now guardian protection even our contacts. I tried to de-register the handset but I do not know the pin. When I put in the system PIN 0000 it rejects it and I can not move forward. I do not want my contacts to go through the call guardian process. What should I do?
