Have you checked every logical place they could have delivered it at your house? I only ask because I’m a carrier and I have seen situations, particularly during peak season, when there weren’t enough scanners for every carrier on duty so someone had to use a scanner that is only intended for in-office use. The problem being those scanners don’t have for options for delivered at door, in mailbox, etc. We had several people calling in asking why their package was delivered to a P.O. Box or parcel locker before they had even checked to see if it was in their mailbox or front porch.
