Billing extra cost on my acc since i had connection issues

Since August i have been trying to sort out my connection and billing charges on my dstv account,,, i call the customer care centre twice a week due to extra charges being billed to my acc between 23/08/2019 to 31/08/2019.... i was told by 1 of their agents that there should be a credit reversal of R234.87 but still to date my dstv has been disconnected. on the 12/10/2019 the evening 21h00 one of the agents advised that they have a backlog of 3 months on queries, mine is still new so they will call me when they get to my query ... i asked her whether that would be after 3 months and she said yes, so my question who is paying for all the calls i have to make to DSTV and holding on for so long. i pay my subscription fees monthly but for the month of October i had no joy of watching ... my money down the drain, everytime i call i have to explain that i do not owe any monies to dstv... they keep on saying they will call me back in 48 hours or a manager will call me back but nothing.. is this still worth paying for dstv... in desperation i paid R200.00 on 13/10/2019 but still my services is disconnected.
