DSTV Multichoice and their "approved dealers" harass historic customer.

Dear DSTV Multichoice and their "approved dealers" I understand with streaming service providers that your outdated business model is at risk, this however does not give you license to call and harass me to take up your products... I just got another call from one of your affiliates, +***0 claiming I was an existing customer and furthermore refusing to acknowledge my request to not be called again... even when threatening legal action... just stop it... complaints go to more people than compliments this is basic marketing, get it right!
