Up and Down Pathetic Service

On the 9 May 2015 2 devices were upgraded.The call centre agent advised I would receive the devices on 12 May.Only one device was received on the 15 May.Later that day it was confirmed that the courier service had sent the device back to vodacom.Vodacom advised me they reversed the phone and re-ordered,and I would receive the device on the 19 May.On the 19 May I was advised by vodacom the device was reversed though nothing was ordered and I would need to call back and re-order.I then contacted an agent,she sent PINS and asked security questions,I was shocked at this as no questions were asked the first time round and no pins were sent to the device.Upon answering these questions twice she told me the questions were answered incorrectly,which I had answered correctly.She later told me she cannot assist me and I will not be able to get help from the call centre,I need to go into a branch, this is a huge inconvenience.I am very annoyed by the pathetic up and down service Vodacom has given.
