Contract cancellation

Good morning, I have the line that was ending on the 01 of August 2817 I personally went to telkom direct store to enquire about the cancellation process of which I was advised to hand in my cancellation form on the 01 of July and I did exactly what I was told...few day after I received several missed calls from telkom and when I called them back I was told its was their back office they wanted to confirm of which I told them its very hard for them to get me on the phone due to the nature of work im doing then they suggested that I give them the alternative person that can confirm of which I did but still the cancellation has not been actioned, I phoned again the call centre to follow up on the 18 July I was told that they will escalate my matter and I told the call centre that I want my line to be cancelled immediately cos I dont see a need for them to confirm my cancellation since I have filled in the cancellation form which confirms that I no longer need those services what is it so hard to do the damn cancellation....on the 25 July I also follow up but still the line is not cancelled telkom is very unprofessional, pathetic, and very inconvenience I have tried to speak to the team leader that was in charged when I called I was told she was busy but even the agents are unhelpful and unprofessional in handling us, the service is **** , please help me with this cancellation cos I don't want it anymore and I will be charged for something that I have long requested to be cancelled. Telkom has breached the contract that I have signed with them failure to cancel the contract when the term ended. I would like to get a feedback my number is ********** 053 my id number is ********** 403082
