Blatant disregard for customers request for a cellphone contract cancellation.

Two years ago we had taken a data contract with telkom. The two year ending date was in October 2017. A request to cancel the contract was submitted before the ending date. To this date 15 December 2017, We still getting billed for something we no longer require. This is not the first time telkom has failed to cancel contracts, as we had many with them. They deliberately ignoring emails and our wishes. Never again will we take a contract with telkom.
