Usps Says My Package Was Delivered But It Was Not. In my city and zip-code. Oh hey look this is a surprisingly common question.

But the refund is not provided for every mail class. If its still not there contact your local USPS post office. In the case you had booked your mail item with a service that offers a money-back.
I just had the same thing happen.
For example i just went to my mailbox and got my package that still says in transit Meanwhile I have another undelivered package that was marked as delivered yesterday. I just had the same thing happen. I have an expensive package coming from Japan via EMS and USPS tracking says it was delivered an hour or so ago but its not here. Whether you are sending it or receiving it your mail is important to you and the US.
