Wrong information due to errors

So I contacted DSTV call center yesterday as I would like to make a payment and reconnect my service. There was an automated response saying I need to pay R338,62 for my service to be reconnected and then the next payment will be 25 December 2018, I then ended the call and phoned again as I know with DSTV they always have different amounts and this time I recorded the call that said the same thing on how much I owe and a SMS with the amount was sent and a link to do the payment. After that I called to speak to a consultant who was arrogant and rude as hell and I explained to her my frustration and she started getting a attitude. She then told me I need to pay R938,62 and I refuse to pay this amount as the SMS and recorded line I have states clearly what I need to pay and she advised that there is a system error and has been happening a lot. Once there is a system error you as DSTV need to remove that error with immediate effect and now you want me to pay extra because of your system error I will be taking this further with my recorded call of the automated response as well as the recorded call with your arrogant and down right rude consultants. You guys should be ashamed of the bad service delivery you have and making the customers pay for them.
