I know the feeling. When I lived in the UK I had the same until we went ex-directory.
My parents, who are in their seventies, do live in the UK and they receive at least five or six calls a day. Unlike yours these are mostly not from call centres but are completely automated, so the most amount of pleasure you can get is simply to put the receiver down. It's like having Marvin the depressed robot phoning you every other hour. Contacting BT has done nothing at all and like you they are planning on switching numbers. Personally, I think this nothing short of corporate harrassment.
