Still billing me for a closed account

<p>On Thursday 12 May 2016, I cancelled my account with Telkom. I also went in to the branch, queued for ages and cancelled it in the Lakeside Mall branch in person. This cancellation was re-confirmed on the 4th July 2016 to ********** <p> </p> <p>The final amount of R 142.33 was taken off my account on 01 August. Now I have been billed AGAIN and another R199 has been taken off my account.</p> <p> </p> <p>I cancelled this account because of continual pathetic service - now it seems Telkom still cannot get things right!!!</p>
