call blocking

Not sure if chat is the right place but I am new and cannot see how to start anywhere else.

Have you joined the BT call blocking arrangement? I joined in November. I have had a 'guardian' phone my daughter bought for me a couple of years ago. Last year I put the house on the market and had difficulty with the agent. When the contract finished in July I suddenly started getting a lot of calls each day. They would ring, wait long enough to listen to the guardian recording instructing callers. Now most people know my email address. They also know I am disabled. Each time the phone ring I would get up and prepare to pick it up on the guardian phone (I do not have a mobile). After listening to the recording whoever it was rang off. This went on several times. At first I thought it might be computer generated but it would ring early in the morning and after office hours. When I heard about the new call block system I joined it and now have caller display and the calls are tailing off. THIS EVENING I was at the computer and it rang so thinking it was my DD I picked it up. It was an Asian man saying he was from the call blocking department and asking me how the system was working and I said it was a great improvement.

HOWEVER he next asked me if I paid my phone bill by DD each month and I said I did. He said he wanted to remind me that MY DEBIT CARD WAS ABOUT TO EXPIRE and I said it was not, that it had years to go. THEN he asked me for the MONTH it was due to expire and I refused to tell him and said goodbye and he protested. In the end I just put the phone down. I have written to the people who advise on the system and asked if they actually do check up on the call blocking member. Obviously I do not expect a reply until next working week but I have informed my children and thought I would put the message on Gransnet. I would have preferred a discussion group but could not see how to start a new thread and this is not on the list of forum subjects.
