MULTICHOICE "ACCREDITED AGENTS" UNSOLICITED CALLS

I am fed up with unsolicited calls from Multichoice "accredited" agents trying to sell me a new decoder, insurance for my decoders, extended warranties etc. These agents obviously receive my personal information from Multichoice as they know my name and have my contact number. As far as I am aware this violates the law on unsolicited sales callas as well as the POPI act. In one instance the agent who was trying to sell me insurance actually became quite "pushy". Yesterday a call started with confirming my name and then wanted to chat to me about my Multichoice account. When I asked what was wrong with my account she launched into a sales pitch for a policy to cover my decoders, dish installation, possible breakdown, call out of technicians etc. I ended the call after politely declining.
