AFTER 3 MONTHS VODACOM CAN STILL NOT ASSIST WITH UPGRADE AND SIMPLY CANCEL UPGRADE DUE TO NO STOCK

I started with request to upgrade June 2021. No stock on the device I wanted. After several weeks my upgrade was cancelled and I was not notified. Re-upgraded 11 Aug 2021. No stock AGAIN! on back order. I followed up last week and was told the would have stock 27 Aug 2021. Called today. Upgrade cancelled. Nobody knows by who of why. Told nothing they can do to assist I need to re-upgrade again?!?!?!?!?
