Failed Upgrade

I was due for an upgrade and I have done an online upgrade on the 11th of December 2023, which at that point the device was still available. A week or so goes by, when I checked in with them the device was apparently out of stock and back orders take about 3 weeks. Ever since then every time I phone Vodacom, I get mixed messages from them, " oh it is still on back order " , " oh they have not spoken to the supplier in months " etc. Then when I try to choose a different device no one can help me. No one is willing to assist me in anyway. I can not even cancel every because the call center people just put the phone down in my ear. There is no management or any authority that's willing to assist me. The when I started complaining on their Facebook page, they half hearted helped me. They tried to phone me but I was in a meeting which I then contacted them to say I will be done in 10min. Then they rep**** they will contact me on 30 Jan 2024 at 1pm. I am still waiting for some sort of assistance. Every time they say some one will reach out to me. All I wanted is just to change my device. Some one to assist me with out it being so difficult.
