Package upgrade for DStv

I’ve experienced very shocking poor service from multi choice DStv call center. It has been 3 weeks waiting for my upgrade from my current package. I phoned the call center 4 times different days for same issue to get assistance and they keep on telling me that , they escalated my problem to management. I was told their time frame is 48 hours until today ????. When you ask to speak to the team leader you will be put on hold until you cut off . I’ve lodge this complain on the 03 September 2019 up until now and the funniest when I told them that , I’ve tried to do upgrade on their WhatsApp it refer me to call *** which is their call center. We pay heavy price fro *********** agents . Very disappointing , I wish it could be more players into this that offer similar product
