Please remove me from your call center data base - I am NOT interested in becoming a client

Can someone from Multichoice assist, I have asked repeatedly that your call center NOT call me, and please remove me from which ever database I am unfortunately on. Weekly calls from Multichoice. I was a client for well over 10 years, your pricing and content is beyond ridiculous when compared to Netflix and Showmax. I do not, nor will I ever return to Multichoice. Please remove me from the database. Please ensure the weekly cold calling stops.
