no answer on pick-up

someone calling to inquire if I wanted to save on my cable bill.... this is a new number so I asked them how they got it....they replied it just came up on their screen.  Yeah right..... I then told them I was not interested and to take my number off the list.   The persistent pest then asked if they could help me save on my cable bill .. I told them don't have cable and don't want cable and I then hungup.
