Dissatisfied and disappointed client

Once again I am struggling to get through to Vodacom with regards my upgrade.

They have promised me that I will receive my device on the 11.12.2017, which was not done. When I called Vodacom on the 11.12.2017 I was advised by the customer agent that they cannot assist as i need to go through to the online upgrade department when I contact the online upgrade department than i am on hold for 30mins if not more. I am really very frustrated and getting annoyed with all of this. RAM and vodacom is giving me the run around. I was not even informed that delivery guy was hijacked on the 04.12.2017 when the device was suppose to be delivered i was informed on the 08.12.2017 when i called in and than i was advised that they not sure when my device will be delivered as there is a process that needs to be followed. This is inconveniencing me in so many ways possible and the fact that everyone has some sort of excuse is just not helping me at all, This really is pathetic service. Can we have this sorted out today.
