Had a problem with a parcel left in a residential box but the key didn't work... I called and the lady I spoke with was very professional and eager. They got in touch with the delivery person and it was at my door before I could walk to the boxes!


Had the back of mail box pried open ( not the post office fault) . When a few neighbors came outside to talk about the vandalism and possible mail theft it was discovered the contracted out delivery person put our mail in the boxes with the back completely open. I guess a P.O. box is the lesser of two evils


They steal stuff from me.… ugh


It could have been delivered to wrong address. I have gotten mail for people with same numbered address but live on a different named street. You are then at your neighbor's mercy to hopefully return it back into the system and not toss it away.

Unless you keep up on tracking of your packages, your packages will end up missing. This has happened so many times since I've lived here. Tracking will say DELIVERED but the packages were NOT!!!


they lost my package... How can you loose a small sized book that can fit easily and perfectly in you mail box. Worst post office ever. And they misplaced my brothers package and delivered it 2 days late from the expected delivery date.


ya they dont know how to answer the phone ether


Mail has NO actual delivery schedule. It is possible for your mail to come at 2 separate times on the same day. They have a bad habit of putting important mail inside the junk mail pages. Also if you are expecting a package, you should also expect them to force it into your box, if it will not fit otherwise. (Not take it back to the facility for pick up, where it will remain unharmed) If you are lucky enough to get there as they are delivering your mail, expect to wait for them to have a full conversation with each other or someone on their cell phone, before you even think about receiving your mail. After all, it's not like you're waiting for a check, and have minimal amount of time to get to to a facility that can cash it and buy groceries for your kids. (*sarcasm) They claim to have the mail go out early in the morning, so there's no way to get it at the facility. (How did my mail get delivered at 4pm? Hmmm) what are they REALLY doing all that time!?(about 9 hours)

Worst post office ever!
Bad customer service!
Also when they deliver packages to my mailbox, they will stuff whatever package they can into the small mailbox.
I've gotten packages that say "DELIVER TO DOOR" but those idiots just put it in the mail box instead of delivering to the door.
