Inconsistency leading to Disconnection _ Highly Annoyed !!!

My service was disconnected in April, I then went to Shoprite on the 23rd to enquire what is required for reconnection as I do every month, I was informed there's a balance of R300 outstanding, I made a payment of R800. DSTV reconnected from then until Today, the 4th May. Early this morning my service was disconnected, I then called into the Call Centre to do an enquire and I've been bamboozled with the feedback given, between Bongani Tugwana & Harriet Tshabalala I was then informed Shoprite's systems were incorrect, what was due was only R95 plus DSTV took a R50 for a Reconnection Fee & R20 for something called "Pro-rata". Meaning I am left with R635, I was then told there's a further outstanding amount of R500, Never in my time of having DSTV did the monthly premium cost me close to R1200. Ridiculous !!! I want my service to be reconnected until the last day of the month, when I make my next payment. I get paid the very last day of the month. Based on my own calculation what is outstanding should come to R194 - which I'm prepared to pay but I will not pay R500, ONCE AGAIN Never in my time of having DSTV did the monthly premium cost me close to R1200. Ridiculous !!!
