Yesterday I received an email that a package had been delivered by USPS and that the package had been left at the mailboxes, which are down the street on a post with other mailboxes. I went to look for my package but it was not there. Why would the mail carrier leave a package on top of the mailboxes where anybody could have taken it. Not very smart.

Yesterday we had mail for pick up in our mailbox and no one picked it up. It's 3pm and it's still has not been picked up. What is going on with our service?

Why is our mail being delivered late in the evening? Yesterday it was delivered at 8:31 PM. (I have cameras). This is recent before it was always in mid afternoon.

I have problems with the mail from here. A $200.00 money order disappeared from the envelope it was sent in. Additionally I ordered products from online and they were tampered with. They products I received were of less quality when they arrived. I am extremely dissatisfied with the mail delivery person who refused to give me the info as to who I contact to file a complaint.

I have never had nor heard of a post office as bad as the Tregallas location. I have had many problems with this place and it seems it just continues. Twice I have had mail that never reached it's destination that caused my payments to be late. I received emails that claimed my package was delivered however when I confronted the mailman it was still in the back of his truck. But worst of all my tax REFUND CHECK was on the ground. Are incapable of performing their job or just stupid!

I find it very frustrating when you drop off a package you say it’s been delivered and you walk out and it’s not on your doorstep and it’s not nowhere else just right when it says it got dropped off your t told to do an online filing I have to get through all that nonsense it says you cannot file online claim because it wasn’t insured so what it was the US PS Antioch you gave my package to somebody else I called you immediately and you couldn’t find it

Your service to my residence has been very horrible to say the least.
Start getting the adresses right. It seems as though your postal delivery person can t read!

Uh Deb, maybe YOU should do some reading yourself sweetie. Then you might have caught that little note a few lines up ... right under the large blue letters R-E-V-I-E-W that read: "*Comments below are not read by postal employees".I suggest you call or write your local Post Master to discuss your service issues. You have a wonderful day now!
