Paid priority mail ,item has not made it to its destination, need to know why its not there.

I went into the office with my tracking number. Magically my stuff was in the mailbox. I think it was the carrier.

It was supposed to be there on the December 1,it was in denver yesterday, the person still has not received it.

You need to call, then. They will need the tracking number of the priority mail piece to track it and see what happened.
