I wish they would - them and BT - I won't be buying anything new from them but they still call despite being asked not to.skier-hughes said:If they call and you tell them not to call you again then they should remove you from their listing.
I don't think there is a legal way to compel them though.
My personal favourite was the "debt helpline" calls that play a prerecorded message then ask you to press something to speak to an adviser.
I like to put them on speaker, press the number then go silent - see how they like the "silent call". Childish but fun!
