DStv price lock.

I got my Dstv explora ultra on pricelock. Little did I Know that my nightmare was just starting, I've been a DStv customer for years...... On the 26th of November I called DStv to find out why they did not debit their subscription on my account and the consultant said it reflects as paid on their system. Then I noticed that it was not debited on my statement, then I called again on the 1st of December around 18:15 and I talked to a consultant by the name of Gugulethu Mthembu or Mthethwa , not sure about the surname. Of which she told me in a rude tone that I should pay R1250 because they could not debit my account, when I quiried the amount and explaining to her that I've been calling since the 26th to ask them to debit, she became igitated and very rude, and buntly said "it's not her fault that they,DStv, could not debit my account" I then asked her to transfer me to her manager and she put me on hold for more than 10 minutes then eventually she came back to the call and said since she's working from home she's not able to transfer me to her manager then she said she will logg a complain on my behalf and one of the managers will call me within 30 minutes, of which it haven't happen. She have since gave me account numbers where I should pay, of which I payed the initial payment plus insurance.... How do we resolve this ?
