Hello. The building I live in has a large package in the mailroom. It’s not for a tenant here. It was delivered by FedEx. It is a child/baby furniture item and really heavy. Please contact me with the name and apartment number it was supposed to be delivered to and we can arrange a pickup.
My building gets mystery packages like that all the time. If you write down the tracking number you can call FedEx and they will arrange to pick it up and return to sender (if you don’t find the owner yourself).
