I sent four packages to NV, they all get there in reasonable time. One has been in Ca. since the 3rd, its been at the Lancaster P.O. since the 9th. They can't tell me why its not moving except blaming it on ground shipping or the truck, which comes back to the one package, there is no reason it should be just sitting. The P.O won't answer their phone, they let it ring then pick it up and hang up, so unprofessional. I'll never ship packages again with USPS, just can't them to get the job done in decent time. $72. to ship four medium to small packages and i just get lame excuses.


Why is the post office closed and my package not being brought to my father's home. This is so unacceptable. USPS 9505515244587115098121, Business Closed 04/28/2017 3:43pm LANCASTER CA 93534 Reply HELP 4 help-STOP to cancel THE PACKAGE IS JUST SITTING IN THE DARN POST OFFICE
