Waiting for an upgrade delivery and Vodacom just cancels the request without informing the customer

I have been a customer of Vodacom for well over 20 years, currently having 3 contracts with them. Vodacom very proudly advertised the IPhone air in February 2026, which I heard on 947. I tried to upgrade online, was unsuccessful and left a call back. Was called back by a consultant, whom I will not name, went through the upgrade process and was told that I can expect delivery in the next few days. I have been waiting, got sms that parcel was handed over to courier who will contact me, three times, but no call from courier... I called Vodacom querying this, each time I'm told that there is no stock and my order was put back. I mentioned that Vodacom does not even bother to let customers know of whats happening, poor consultant extremely apologetic, what else can he/she say as they are trained to apologise! I was not well for a while, but kept on waiting for my delivery. I called again today, only to my utter surprise, to be told that the order was cancelled on 31 March 2026. BY WHOM? FOR WHAT? WHY WAS I NOT INFORMED WHEN IT WAS CANCELLED? I am totally disappointed by this. If Vodacom had called me even once to inform me that there is a problem with the device that I had upgraded to, I would have understood, but to just cancel and not give a damn, is not on! I want someone from Vodacom to call and explain to me what's happening, and how are they going to resolve this. Apologies from the call centre consultants is not required as this is not their fault. The fault lies with the Vodacom execs who do not care about their customers.
