Impossible to cancel a Telkom service

<p>Since October 2016 I have sent a request every month to have my ADSL line cancelled. November I was told that my query is getting attention and I will be credited on my next account as from the date I requested cancellation plus 30 days notice period. I have just received my Telkom bill and as expected I am stil being billed for a service that is supposed to be cancelled. Can anyone help me just to get this cancellation through and processed and done</p>
