bad service from the highest level management

<p> Telkom incorrectly delivered a second device to me 9 months ago. They won't collect it and keep billing me for it. I have emailed, phoned, been to the branches, been to the head office. I even posted on hello peter. They respond but the minute the words escalated to the highest level that's where they stop . So management appears to be the problem not the front line staff.</p>
