iPhone Upgrade trade-in not received
Upgraded from IPhone 15 to IPhone 17. Traded and shipped IPhone 15 to Apple as part of the IPhone upgrade program. Two months later I find out I’m still being billed for my old phone payments along with my new phone. I then find out that the IPhone 15 never got delivered back to Apple. I no longer have the tracking number for the shipment and I don’t know what to do. I feel like nothing can be done, and that I’ll be forced to pay off the IPhone 15 that I no longer have access to.
