DSTV Price Lock PLEASE WAKE UP and PHONE BACK AS PROMISSED!!!

I want to STOP a debit order on a Price Lock deal that expires on Dec 31, 2019. From Dec 1, I started calling Multichoice and the operator told me EVERYDAY that someone from the Pricelock department will phone me to help stop the debit order. TODAY it is Dec 19. Nobody called, and I need to say it AGAIN. " I phoned in EVERYDAY to cancel the debit order, with the same response" "Someone from the price lock dep will phone me back". DSTV, No man, this is not good liaison. What to do after 20 days of NOTHING??? My Price lock deal expires on Dec 31. I want to disconnect revises. If I don't stop the debit order, I pay another month for something that I don't want
