Cancellation of Contract

I have cancelled my contract with Telkom in First week of August I was told it has been cancelled.In September I called them to confirm the cancellation I was told it has not been cancelled and I was advised to downgrade which I did from 80 Gig @ R469,00 to 20 gig @R110.Yesterday(02 October)went to Menlyn branch i was told it has not been cancelled they deducted R469 and reduced data bundles.It is so frustrating cause it seems as if they are not willing to cancel the contract,You will go to their branches they will keep on telling you new story.I don’t want anything to do with Telkom I just want them to cancel the cotract.
