Complaint process designed to ***** your money

Cancelled my DSTV streaming subscription in December. Received confirmation that it is cancelled and service will end on 31 Dec 2023. My account was billed on 1 January. This could purely be a mistake, but the way the support has handled it is beyond ridiculous. I contacted Multichoice to inform them of the error. All details were given through. They confirmed the error. I was told I will be contacted in 48 hours. Nothing I go back, give the reference number. I have to explain and prove my case again. Confirmed error. I was told that I must contact them back in 48 hours. I do that. Nothing has happened. The process start again. I need to prove my case to the 3rd agent. They confirm that something is wrong and will escalate the issue. I must contact back in 72 hours. I do that. Nothing has happened. I once again have to explain all the details and prove my case. Surely the billions they have made off the SA public could pay for a decent support system where the details could be recorded. They make it as difficult as possible and hope you will give up so that they can keep money they didn't earn. *******!
