Systemic failure of DSTV accounts and customer service

I received a phone call from a DSTV representative at the end of August 2018, offering a renewed two-year PriceLock contract, at a reduced rate of R789 per month (I currently paid R949 per month). I agreed to take on the new two-year contract. However, since then, my services have been regularly cut, on the pretext that I owe money - each time, the amount owing being different. This has occurred on an almost weekly basis. I called to complain on September 16th, September 27th, October 3rd, October 8th and October 14th, each time after my service was cut. Each call followed the same pattern: the agent informed me that my services were cut because I owed money; I informed the agent that I pay via debit order and that I can't owe any money; the agent investigated this and confirmed that s/he is unsure why the services were suspended; the agent reconnected the services, informed me that the matter had been referred to the accounts department, and stated that someone would call me within 24 hours to address the issue). However, each time, no call would be forthcoming and, within a week to 10 days, the services would be cut again. There was one attempt to call me back, on October 9th, but I missed this call and no further attempts were made to call me back. Today (October 19th), the service has been cut again.

Moreover, when I agreed to the renewed contract, I was informed that the normal debit order, of R949 would be taken at the end of August, but that the renewed fee would come into effect at the end of September. I was thus extremely surprised, and unimpressed, when, at the end of September, not only was I NOT charged the revised R789, but I was in fact charged R990. When I asked one of the agents about this, she indicated, as always, that she could not understand why I was charged this amount, and that the accounts department would call me back to rectify the problems on the account. This was during the telephone call of October 8th, the only one after which one attempt was made to call me.

Finally, when the initial sale was made, I explicitly asked if the R789 was all-inclusive, and was informed that, indeed, it was. However, I subsequently have been informed that the additional R90 Access fee (for access to PVR services) was NOT, in fact, included and that I'm due to pay R879 per month. This, again, was not as per the original agreement explained to me during the initial phone call.

The situation is now such that I have my services cut every few days, have to make lengthy calls to the call centre, with frustrating results, while being charged more than ever (rather than less), and with absolutely no recourse.
