Ordered Xbox Design Lab Controller, Arrived at Wrong Address

The FedEx driver didn't read the label for the box and delivered it inside of an apartment building that is locked. I cannot get access to the building, even after reaching out to the apartment manager. FedEx told me to contact Xbox for assistance, and I have no idea how to do that since the AI just sends me messages that make no sense to what I said and won't connect me with a human being.
