Awful upgrade process thus far

Upgrading my Vodacom contract via iStore based off this article on MyBB https://mybroadband.co.za/news/smartphones/509882-upgrading-my-vodacom-contract-online-for-a-new-iphone-15-istore-has-a-big-winner-here.html

Terrible experience so far and unable to speak to a human as they don't respond on their WhatsApp line or answer to online chat.

My application is 'submitted' and it's been days. I should've just walked into a Vodacom store.
