Contract Cancellation

I must share my utmost disgust how I am being treated by Telkom. I have been trying to cancel my utterly disappointing LTE contract with them since July 2017. Even before that I contacted, via email their cancellation department but to no avail. Every time I visit a Telkom shop I am being fed utter nonsense that you were trying to get hold off me, yet no missed or received calls are on my phone. Their sales department however got me on their first, I stress first, call. How can the cancellation dept not get hold of me. Further to that Telkom closed my first "official" cancellation case no. ********** 1 without resolution. This I was told, because Telkom cannot keep cases open for too long. This is why there SLA makes for good reading because they just close a case without resolving it. I have now a new Case ********** 4 and have yet to hear from them. I am so disgusted that I expect Telkom to cancel my contract with immediate effect without any penalties. Their service not only in providing LTE but also in this case is shocking.
