Telkom going down

I took up a contract with telkom in September 2016. I went to the store last month and they advised that i can cancel my contract in september for October. i called the call centre today, and the agent told me that my contract is only 21 months old which is lies. I told her that I have proof of the day the contract was taken out and she told me that the contract documents i have is not valid... like really telkom???? i also advised the agent to double check as my account may have been in arrears which i am upto date with payment but then she refused and was very rude. she really didnt seems interested to assist and neither did she give me a good customer experience, she did no investigation neither attempted to or assured me that she will look into the matter. sorry telkom but ur services are extremely pathetic and i dont wish to do business with u guys again. i need this sorted out and the branch also advised that my contract ends in october. i cant believe how this agent refused to assist..
