Pathetic Service when cancelling subscription

I've been trying to cancel my DSTV subscription since November 2019. When I first phoned i was told i was on a contract which expired at the end of December 2019. I phoned back in January 2020 and was told that my contract only expeired at the end of February 2020. I told them to cancel the subscription, so that it would end on 29 February 2020 and there would be no deduction for March 2020, Image my frustration then when they deducted the subscription for March 2020. Upon phoning the "help" centre I was told that I had only cancelled my Showmax subscription, not my DSTV subscription; when I asked to speak to a supervisor I was transferred to a closed switchboard and my call was terminated. Even more irrate I phoned back, and because of their completely ineffecient system I had to resubmit and reconfirm all my details again. I was eventually put through to a "supervisor" whose "customer care" s****s need a lot of work. Firstly I had to reconfirm all my contact details because apparently their system doesn't have the capacity to show that this has already been done (multiple times) on that call already. Then I had to listen to this woman being sarcastic with me and telling me that I need help because I am frustrated with the pathetic service multichoice provides, and delaying putting me through to the insurance desk so I can cancel my decoder insurance, so that she can continue with her sarcastic remarks.

I'm told that my subscription is now cancelled, and that I will receive a refund, but there's no guarentee that it will happen because DSTV service is so pathetic. I hope though that it is cancelled, because I never want to deal with this company again.
