I made a mistake and traded my iPhone 7 instead of the iPhone XS. I could not cancel my pre-order for the iPhone 12 mini even though I just ordered it couple of hours prior. I waited to receive the phone on 11/13/20. I took it to 2 corporate AT&T Store and they could not return it and recommended to ship it back with the return label. It's been 7 days and stuck in Sparks NV Inducted into Pitney Bowes Network since 11/22/20. Support to go to Fort Worth TX. AT&T is so fast shipping phones but their return is so shady.
