Acc cancelled but still being billed

I have cancelled my Telkom line on 02/02/2015 as I moved. The lady at the Telkom branch confirmed the Cancellation order on 02/07/2015. The cancellation was done at the Festival Mall Branch, online as I wanted to ensure it was done properly. On 03/07/2015 I received an msg to say that my account is in arrears with the amount of R1057.51and the line will be suspended. I've emailed and reported the issue on the Telkom Website multiple times, just got another reminder that the outstanding amount is R1279.15. I have escalated the complaint yesterday and still have not received any response from Telkom! This is really pathetic!
