I cancelled my Telkom nearly a year ago and am still being billed!!!!

<p>I sent a cancellation request to Telkom in April 2016. After this I still continued receiving bills. I sent another request, attaching my original cancellation form in July 2016. I still continued receiving a bill. I then went into the Telkom office at Lakeside Mall, Benoni, where they AGAIN took all the details and advised that this will be sorted out. I am STILL getting bills from Telkom. I have phoned my original number and it states "the number you dialled is incorrect" so I presume that this has been cancelled. WHY AM I STILL RECEIVING A MONTHLY BILL, WHICH IS ACCUMULATING!!!! when this account was settled in full. The original number is: ********** 548</p>
