Telkom Mobile upgrade disaster

<p>For over two months now I have been called by agents of Telkom to do an upgrade on my portable wifi accounts (2). I agreed and went through the whole procedure but heard nothing further. I called several times and eventually was told that the upgrades had not been done. So, we redid them and now the packages have changed according to my account but the new device has not been delivered, as promised. I have called 6 times this week - I go around in circles telling the whole story again and again but still no devices despite being assured that a manager will call back. No direct number to upgrades or specific people, no names given, no reference numbers = NO SERVICE</p>
