3 months, telkom has not revered incorrect charge

I logged a complaint here<br> http://hellopeter.com/telkom/complaints/charged-installation-for-line-that-want-installed-***<br> <br> I was billed for a line installation that never happened. 3 months later and telkom has still not reversed the charge. No feedback was given and no one contacted me. <br> <br> Impossible to get hold of the call centre.<br> <br> All I want is for the charge to be reveres ed so that I can pay the balance and close the account. <br> <br>
