Contract cancellation

I am frustrated by Telkom mobile and their lack of feedback on the premature cancellation of my contract. Every time I phone to enquire I'm told about the retentions department who do not bother to provide me with any feedback.

I phoned Telkom mobile at the beginning of August 2017. On the 15th of August 2017 one of their agents called me to give me a settlement amount of R1400.00 which I duly paid. I kept on calling and was told that there's a turnaround time of 21 days from 15 August 2017. When I logged in to their app I realised that the R 1400.00 was now reduced and the issue is labelled close. But the contract is still continuing. Every I phone it's like their agents want to talk me out of cancelling my contract. In all of this my case was assigned reference number: ********** 2 for data SIM number ********** 094.

Please assist me as I'm now running out of patience.
