False information

My Telkom mobile contract of 2 years was ending on the 12/10/15 it was for a S4 mini on a smart plan 100. The plan consists of 5gig data, 100 talk time minutes, 150mb all time network and 10100 wifi which cost R269. I went to the Gallaria mall Telkom to fill in a cancellation form. I got a call 2 weeks later from Telkom and a guy called Moosa spoke to me convincing me to stay with Telkom & this time il only pay for the data and minutes since my device is already paid up. He said i stil get my same data amount and voice minutes for ONLY R99!! I WAS SHOCKED & asked him to repeat himself. I then agreed to it. He said because im a loyal customer he will throw in 30 voice minutes free for 6months since im staying with telkom. So end of October came and i paid R99 but end of November i was billed R931 & received another bill for November for R725 . When i called call centre they said my contract ended and im paying full price for data now. I told them Moosa called me and stated il only pay R99 , they said they got no record of that. I then spoke to Norma from the chat dept she said Moosa didn't say R99. I told her listen to the voice calls. Until now no call from telkom. Now what??<br>
