Feel every moment of my patience being tested.

I am so disappointed in the services received. I cancelled my Dstv account on the 31st August 2020 and requested a refund on my payment. I then received email confirmation that the refund would be processed within 24 - 48 hours. It is almost the end of September and no refund has been received even after contacting customer services numerous times. I was promised to be called back by a contact centre manager and have yet been contacted. If I was a R1 short on my payment I would have received multiple calls and my Dtsv would have been put off immediately. Now that I am owed I have not been contacted once. please help
