That's what the SMS i received said, but 2 of the 3 consultants said, it might not. I've logged into the MTN App and it shows billing for November at the Discounted rate.
They have no decent downgrade or upgrade deals ATM so suggested I wait till next week.
The contract actually ends today. So billing would be from 6th Nov to 5 December.
If they Bill me the full amount, it's R1100 more than usual, i'm willing to take that risk as this 400gb plus 400gb package is unbeatable. If anything the upgrade will be in effect from 15/16 November, which means they can only charge me pro rata from 6 Nov to 15/16 Nov. (I HOPE) LOL
