Who called from 3134421700

I received a message on my answering machine concerning a missing package through the post office.  When I tried to call them back, the message was the number was no longer in use or had been changed

It's the US Postal Service in Detroit

is there an updated phone number for this location? do you have a street address?

leaves no message.  I let my answering machine answer all calls that I am not familiar with the incoming number.

This is the USPS; they called me to follow up on a missing item.
