FedEx lost Iphone

Hello I sent my iphone 11 back to Apple using the label that apple provided me via FedEx. However the phone ended up in Canada and the receiver reached out to me when they received it. Fedex clearly lost the phone and Apple is refusing to help because they are telling me to reach out to FedEx which I have done several times (they sent the phone to a random person in Canada) for help with a device they lost...? They can't tell me how to proceed with FedEx and I have provided proof of the device being received by the wrong person and that person handing it off to FedEx in Canada.

Basically Apple is refusing to help me or even review information/evidence at all
