Worst service from Vodacom

I have been trying to do an upgrade since 2021/03/03. For the fourth week I've been told that the device I ordered is on back order. I told the consultant 4 times just to change the color from white to black in order for them to send me the phone. EVERY time I'm told it is done to phone a week later and hear that I'm still waiting for a white phone and it is still on back order. Yesterday after sending an e-mail a lady Hlulani Mathonsi phoned me and together we phoned the retention department because by now I'm told that my upgrade is now totally cancelled! I was promised by the consultant that everything was again captured and that Raymond from the Retention department will phone me within 20min and Hlulani said she will phone me again today (2021/03/25) to follow up on my query. Now 24HRS later I still have not had a call or answer to my mail from Raymond or Hlulani and when I call any of the call center numbers they just say they are unable to transfer my call. I even tried speaking to a manager or someone in a senior position, but according to the call center consultants they cannot transfer my call to a manager.

This is the worst service I have received in my life because as I am writing this review my upgrade is still not done.
