Order System & IT System Error Repairs not done for 14 days PLUS

On the 13-10-2017, I have called the call centre to order an upgrade from my 2Mbps Line to a 4Mbps Unlimited Home ADSL. The operator told me that he have a problem with the system coming back to him for confirmation, but he have send it to the technical department and the order will proceed. On the 17-10-2017 the order ref: ********** 27A was listed on the system, but I got no notifications from Telkom. I called them and they told me that it will take 5-7 days. On the 24-10-2017 I called them again(Spoke to Thibosa) and they told me that it will take 7-14 days. Please teach your people in the call centre what is CORRECT/WRONG. So, I wait until 31-10-2017, and I call them again( Spoke to Domiso). He told me that the IT department have not fix the problem yet and the order can not proceed until they fix the problem with the system. I have waited for TELKOM for 18 days and NOTHING HAS HAPPENED. I HAVE WASTED MY TIME to ask them for the upgrade and feel like going to the competition.
