Online upgrade process is poor

I app**** for an online upgrade for an iPhone 11 128gb at R849.99. 1 and a half months later, no one has gotten back to me. I then logged an enquiry on the website and got an automated response. No one has contacted me since. Eventually, I went into a store to enquire and the stores take no responsibility for online deals.

I would have done my upgrade in store but the deal I wanted no longer exists. The same phone and package are now much more expensive.

I am told that I missed out and im too late, but When I tried to apply online no one ever got back to me.

Not happy with the service and the lack of communication with the online department. As a customer its almost impossible to contact anyone who can help.
