Cancelling a contract that has come to full term becomes a nightmare

I called Telkom before the 17th the expiry of my contract and I was advised that it will automatically disconnect on the 17th. I discovered on the 20th that the contract was still active and I called Telkom to cancel the contract and the consultant said it will be cancelled on the 30th Of November and I will pay a full month. Which I agreed, its the 2nd of December and the contract is still active and I called again and the Consultant (Bianca) - 806 614 559A to cancel immediately - why must I pay for the Telkom teams' incompetence. I refuse. My family must not eat because you cant do a simple request of cancelling a contract that has come to full term and provide me with misinformation. Dispute number is ***0
