MTN Response Shocking

MTN you keep focussing on my July visit to the WONDER JUNKTION where I signed for a limit of R200.00 after receiving your invoice for the amount of R2800. This contract has been a 2gig data package from day one when the contract was agreed and signed. The data cap was from the very beginning for only 2gig as it was for my daughter that is a student. Any normal person would recognise that you can never give a student an uncapped internet contract. The payment history will clearly show that the monthly cost was always R119 and after the price increase it went to R125. I never changed any thing on my original contract when I renewed the contract!!! Within this framework PLEASE go back to my account history and then explain who changed the contract to uncapped, when the changed contract was signed and by who. I do seriously feel that MTN is not answering this basic, but significant important, enquiry of mine. GO BACK TO THE BILLING HISTORY AND EXPLAIN WHY THE CAPPED 2 GIG CHANGED TO UNCAPPED. STOP PLAYING WITH FEEDBACK THAT DOES NOT RECOGNISE MY QUESTIONS AND FOCUS ON EVERTHING BUT THE ORIGINAL CONTRACT THAT WAS NEER CHANGED BY ME AT ANY TIME PRIOR TO JULY 2015!!!
