Contract cancellation

This is the 5th report-Telkom Mobile (Thulani Mokoena) does not want to cancel my contract and yet l am without a phone. Telkom has been telling me that the matter is being handled but there's no response and I continue to pay their subscription. Cancellation forms have been sent to Thulani from December 2015, three times with emails reminding him to action these but he's keeping quiet while I suffer. This is what happens when you appoint people that are not ready to head departments.
