Cancellation of LTE Sim card

- Sent through a cancellation form to telkom mobile on Dec-05.<br> - Received no feedback so called on the 15th and was told that the sim will be cancelled in the new month.<br> -Jan 01-2016, sim card is still active and I am being billed. Called again, and was bounced back and forth between consultants like a ping-pong ball. Eventually was told that a case has been logged.<br> -February 1st and the sim card is still active and I am being billed for a useless sim.<br> - Called yet again and was told that a case had been logged on the 1st of Jan and \Someone is working on it\".<br> - I explained that no one has contacted me to date and this is now the 3rd month going. <br> - My request to speak to someone else was denied and was told they would call me, however for the last 8 weeks no one has bothered to call.<br> - I refuse to believe that it takes 3 months to cancel one lousy Sim card.<br> - My reason for wanting to cancel the sim card is because it does not provide the LTE coverage as promised by Telkom. I therefore use home line.<br> <br> This is extremely frustrating."
