At what point is a situation so convoluted that it can be considered an edge case? Because this story seems like it would qualify! Not only did someone's bank account number change without intervention but it seems Apple also got something wrong about the purchase on two different occasions (saying OP bought an iphone, not a macbook and applying the trade-in to their card without confirmation)...I take your point. But, wow.

Im frankly surprised AC works this way, all of my interactions with AC support and Apple makesit seem like one wants nothing to do with the other.
