I placed an order for an unlocked iPhone 18 Pro Max for a total of around ~$1,400 of which I paid for using money from my Apple Account (aka gift card) not a credit card. On the order I also included a trade in which was a iPhone 16 + which had a trade in value of $430. This order was for pickup and the Apple Store and also precessing the trade in there as well.
On Friday I went to the store did the transaction, trade in was accepted at the full amount and the rep had me choose a credit card in my apple watch to refund the $430 to. Didn't think anything of it when I left.
Next morning I wake up to an email that the trade in credit was cancelled from my credit card. After looking around it seems the in store rep should have given me a gift card to apply back to my account since that was the original source of payment.
How can I go about getting my trade in credit? I have an email clearly showing it was brought in etc.
