I give up on DSTV

DSTV used to be the most popular and best entertainment network in SA. But over the years it's gotten worse and worse and certainly very unpleasant to deal with. I was contacted by DSTV agents and offered a new decoder. I was never told that I will have to pay cancellation on the old one or that I will have endless problems. it took a month to install and since then I am not able to adjust the volume on my decoder. they say it's my tv, but it worked fine with the old decoder. the first month I was charged double (2 decoders and 2 insurance). I did not have the R2500+- in my account to pay for this so the debit order was returned. this caused a string of issues as every time I called in for help the bill got higher. at a stage the acc was R3222. Now remember every time I call, I have to pay the call and you hold on for no less than 30 mins and once someone takes your details and says hold, please you get cut off and must call again. so, after almost giving up I was told it will be referred to a team leader and fixed. I paid the acc for one month only, but it still showed on the app that i owe R1800+-. then a few days later my viewing was disconnected. I called in to asked for help and was left on the call for 45 min. I don't know anymore. will someone sort this out or is it bests to just cancel my DSTV. I still don't know how much I am supposed to pay monthly. my insurance is still not reversed. I cannot keep calling and holding for hours as this costs money. when will I be assisted?
