Also, according to the USPS,
The absence of a delivery scan on a mailpiece does not necessarily indicate that the item was not delivered. It is possible the piece was delivered but the scan was not captured. If you think this has happened, you may wish to contact the sender or recipient to confirm delivery of the item.
If there are no delivery scans in our system, and you know the package was delivered, the sender can request a refund for the USPS Tracking® fee (but not the postage). This is applicable only to USPS Marketing Mail® parcels.
If you placed your order less than 120 days ago, then please just click the contact us link in the top right of the page!
