To be honest post office is the worst. Mark your address if it isn’t. You might just live in the ghetto and someone took it off your porch don’t you have one of those camera door bells???
Because it’s probably easier to replace it then it is to find it and re deliver it. Things like this happen sometimes just be patient.I don't have a camera doorbell. The one time something was lost it was resolved. But I was checking my phone message and I had 3 messages from UPS asking me if a replacement was sent out and whats the tracking on it. She seemed more interested in the replacements than the lost .
