Hello. On saturday 8/29 I received an email saying that a package I was expecting was not able to be delivered. As of today 8/31 I have still not received package. I have ordered this package twice before ande had no problem. Also, on 8/30 I received a notice from Amazon telling me that another product that I ordered had been left in my mail box but it was not there.

The lobby at the 20th St West facility is no longer open 24 hrs. I was there at 10pm last night and the doors were locked. They've probably had too many problems with the homeless using it as a hotel room.

I have recently not received two deliveries that were tracked to have been delivered to my mailbox. I called the post office on this last one and it was not resolved. Was supposed to get a call back after reaching to the mail carrier but no call. I also constantly get other people’s mail. Extremely frustrating!

I am aware it is the Christmas rush. I have called several numbers which rang and rang (no one answered) why have a phone. I am trying to find my package you report was delivered NOT. I guess I have to go in person to the post office to find out anything. So my question again why have a phone or a web site.

Despite my submitting a package pickup request a day in advance, my priority mail was not picked up on the 17th of July 2018. Don't they inform substitutes if the regular carrier is off for the day?

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.
