Unable to cancel landline

<p>I have been trying to CANCEL my Telkom line since 29.02.2016. </p> <p>I have sent my request via email and visited a Telkom office in Bayside centre.</p> <p>In the interim, i have been paying my account every month in order to avoid been handed over and to keep a clear credit record.</p> <p>I even have the gentlemans email address who assisted at the Telkom branch and even he is not answering my mails.</p> <p>This is PATHETIC. I want my line cancelled immediately and a credit refund paid to me for 12 months or more.</p>
