Yes, unplugging the phone might work, but it is not really practical when you have elderly relatives who may need you.
I do not get any calls to my mobile...it is mostly switched off until I want to use it.
I do not give out my mobile number to commercial businesses and I am not on facebook.

It is only recently I realised that the Council(from the Electoral Roll) can sell your details on to businesses.......I have now ticked a box that prevents them from doing this...but I guess it will take some time to have an effect.
