poor service and not taking their clients seriuos

Cancelled the contract the contract with Telkom on the 06/02/2017 but they still bill me. I called numerous occasions where they confirmed that they do see my cancellation same will be handed to the senior but nothing. To date they still bill . They have now referred the matter to the attorneys which referred the matter back to Telkom since I have proved that the contract was cancelled. Telkom to cancel my contract and stop billing.
