Tracking #9505514367018085112706 says it was delivered 3/28/18 to my mailbox. It isn't there, so where is it?


I mailed a box from Ohio to my son in Vacaville. I paid for shipping guaranteed to be there in 2 days and he never received it. My daughter in law went to your post office and you could not tell her where it is. My tracking number says it was delivered to a parcel locker. What a bunch of nimrods you are.


Looking for package. Tracking #9341989704090084374375 Indicates on way to USPS Jan 7 @ 2:45am. Not received as yet.
