Unable to close Telkom account

<p>I emailed Telkom a request to cancel all my services on 29 March 2016 to be effective 29 April 2016. I did receive a call from a Telkom representitive who assured me that my request would be actioned as requested.</p> <p>At the end of April I received my bill including line rental for May. I called Telkom again on 4 May 2016 (***) to have them terminate the services and issue a corrected bill.</p> <p>As of today the termination has not been done and I have been contacted by Telkom which I was assured would appen within 10 days of my contact on 4 May.</p> <p> </p> <p>What do I have to do to achieve such a simple request?</p>
