MTN Online UPGrade misinformation

I've requested an online upgrade of my phone on 17 Dec 2024, but after many inquiries found out there was no stock available... my email to MTN speaks for itself.

"Dear Customer Care Representative I’ve called MTN (135) and the *** number more than once this week to find out what is going on with my application (order ***). I also enquired at MTN Brooklynn. The final story is that there is no stock for the iPhone 6 Plus I’ve requested. I am highly upset about this because when I made my upgrade request with the online consultant on 17 December 2024, he said there was stock available - otherwise I would not have proceeded with the upgrade! I can fully understand 3 to 10 working days for completion of this process, but I have thus been misled by MTN about the availability of the phone.

Can you please provide me with a satisfactory answer as to why your consultant said there was stock available?"
