Unhappy customer DSTV

I am a very unhappy customer of DSTV, since August because my services was disconnected on the 5th August 2022. When I went to pay they said I owed 1300, because my last payment was in June. My understanding is that when you don't pay an your billing date they give you few days and disconnect you. So that didn't happen to me and I call their call center for the whole month of August but every time I would need to start my story from the beginning. I spoke to over 3 consultants and every time I would need to start the story from the beginning. Last Wednesday I went to N1 City and still I didn't get any joy as they say I will need to pay for their inadequate because someone failed to do his or her job and now I need to pay for that.
