Don't waste your time with ATT promos
I kid you NOT, ATT just did the same thing to me. It started last July 2022. I decided to trade my phone in and use their promo of 800 off in a new phone. Sent mine in through my local post office and just like you, it says stuck in transit. After getting the run around with ATT for over 6 months and them promising the credits would come every month because I'd call, yesterday 02-16-2023 they finally said we can not give you credits on a phone they don't have in their possession. Thanks for stealing my perfectly good phone and roping me into a contract with full price payments. After this is paid, I will never do business with ATT again! Been a loyal customer for over 18 yrs....
