Subscription service cancellation

<p>Since May 2016 i have tried to cancel a monthly payment of R411.25 for a business line that we no longer use.</p> <p>I have been to the Telkom store, I have emailed and phoned them plenty and i still have not been helped.</p> <p>I just received another Telkom bill. How do i get Telkom to cancel this line???</p>
