Finally got UPS tracking! Delivery scheduled for 9/26. Was charged on 2:19pm (PDT) Friday for iPhone 7 MB and iPhone 7+ MB. Details in my signature below. T-Mobile's site and app still says 'Being Processed'. Received no text or email from T-Mobile regarding updates either.
Also, my reference numbers do not match to anything on my T-Mobile account. I checked account number, order number, my phone numbers. So if you were hoping to track it by reference, I am not sure how much to trust it.
@Kylee0300 I think now is the time you should keep refreshing that UPS myChoice page
