Multichoice Bullys

I used to subscribe to DSTV but eventually had to cancel my contract due to the continuous price increases. I was on a month to month contract. DSTV then gave my phone number to SHapiro Sheik De Vries and Associates to harass me daily to try renew my contract. I have requested SSDA repeatedly to remove my number off their mass marketting contact list but they refuse. They even provide false contact numbers for their customer service center. Shame on you Mutichoice for becoming a desperate bully
