Binding people to false contracts

Ive been having a cell contract with MTN and the contract ended last year and whn i called on 15/11/2017 to discontinue my ny contract. Spoke to Thami Madikane(ref ********** 58) who further sold me a month to month data dundle worth R69 . He said if im not happy with the deal i can counsel it anytime. Indeed i was not happy with the deal. On the 31/05/2018 I called contract department to counsel as per agreement with Thami Madikane, This time I spoke to Busi Khumalo who told me that they can't counsel this deal because I was put on a 24months contract, she further said she is escalating this matter to her supervisor who will listen to call recording and they will contact me in 24hours to give me feedback(ref ********** 97). No one got back to me in 24hours, Then i called again on the 01/06/2018 and spoke to Nokuthula Macele who told me to be patient they will call me by end of business day. Still no one contacted me. I then called again on 09/06/2018 and I spoke to Charmaine Matuba who now changed the story that the other two consultants told me, she said a call recording takes 7working days but she can't help because their contracts department does not work weekends. MTN is binding people contracts they did not agree to, and when they have to answer they pull u from pillar to post.
