i purchased 2 Iphone 8s recently and when they arrived and i put my Tmobile sim cards in them they wont work and say the phone is locked to ATT. So i went to the AT&T unlock website and it says i upgraded recently and have to wait 14 days. I do NOT nor have i ever had an AT&T account, so this makes no sense. i tried the customer support phone number as well as going in store and no one knows what im talking about. i just want my phones unlocked and no one wants to help.
