They still want me to pay for a contract which I terminated

<p>I took a contract with Mtn in August 2014 for R179 x 24 months, a few months into the contract I realized that the amount had been increased to R189 but I never queried them. My contract with them expired in August 2016, so they did send me a message to say , either I must cancel the contract in 20 days or it will be on monthly basis from the date of expiry. I went to an Mtn store in Randhart( Jacquiline mall) in July 2016 to cancel but they told me wait until the expiry date. I waited and then went to their branch in Alberton city on 05 August 2015 to cancel and they gave me a reference number( ********** ). At the beginning of September 2016, they send me a message stating that I owe them R145, and later on it was R156. On the 12th of September , I then phoned their customer service line (808) and explained that I did cancel my contract, so I don't know how I owe them. I gave him the reference number( ********** ) and he confessed to me that my request to cancel the contract was not responded to in time, so he was resubmitting it to management for cancellation immediately . He then gave me a new reference number( ********** 40). Within a space of 2 hours I received a call from Mtn , saying I must pay the amount, to avoid further action. I tried to explain my story , but the guy told me , I did not cancel the contract in time , so I'm liable to pay. I gave him the first reference number which I got from the store to check and he told me it's not in the system, he can only find the new one ( ********** 40). I asked him if there is a lot of Mtn companies, because if it was still the same Mtn that I spoke to in the morning, the records should show. We ended the conversation as he insisted on me paying, later on I received a warning message with banking details to pay the amount immediately.</p>
