Horrible service!! My package arrived at this facility on Oct 21, 2020, and is STILL waiting to be sent to my local post office for delivery. It is now Oct 27, 2020, and NO ONE from that facility has contacted me about any issues they might be having. My local post office tracked the package but can't do anything but wait on these people. Very disgusted.


We just moved into a new office with a new vinyl sign attached to the glass sidelite beside the glass main double doors. My package wasn’t delivered because the effing Moron mail person said our HUGE office was vacant. I needed that package! So I checked the USPS Tracker and the moron decided to send it back to Maryland. Why the he’ll are these people so lazy that they can’t check out the Suite to see that it is indeed occupied! Talk about a pain in the ass type situation! What’s the average IQ there? Why can FedEx and UPS figure it out but the USPS morons can’t? These people frustrate the sh!t out of a person!


If you hate having extra time and gas, you will love this post office and all of the others in the area, because they will surely waste plenty of it for you when you drive over expecting to drop off a package only to find the parcel box full. Nobody there is smart enough to realize that if something is clearly way to small, its time for a larger one, or an additional one.


Post office always nice and clean, however, there is standing water in front of post office on 1st street in ☺️Tustin. It is stagnant, smells and could breed mosquitos. Not sure what the source could be. The plants do not appear over watered. Please correct. It’s very unpleasant.


Mail lady left key to C box, I put it in it won't turn my package is locked in the box. 17552 Vandenberg Lane apt 14, tustin, CA 92780,please advice mail carrier, thank you


How do I get the mail delivery person to close the mailbox door? It's left open about once a week. The door works just fine. Thank you, Diane Lowderback
