Shameful Upgrade

I have been a loyal customer to vodacom for many years and have a number of lines on my account. In the past week I have been trying to upgrade my one line, in the first case was helped by Thabo at retentions, selected a s20+ Black, this was then confirmed the following day by another agent. When I didn't get delivery after rescheduling my days to be available, I called the retentions and spoke to Ayanda who advised me that the upgrade was canceled because the device was no longer available in Black. When I asked why I wasn't notified she explained she doesn't know its not her job. Very professional. I then last night via online upgrades did another upgrade for a Note 20 Bronze. Today after the mess of the first upgrade I contacted the online department to confirm that all was good with the upgrade only to be told that it had been canceled because the bronze colour is no longer available. Once again vodacom did not notify me so If I had not called once again I would have wasted my time waiting for delivery. So I did change the phone today to a grey colour. Who knows if I will get this one. So please vodacom can you let me know if I will indeed receive this upgrade and I want it by Friday as I am tired of sitting around waiting for Vodacom to deliver. Really Disappointed
