My package 9361289676090455604233 is listed out for delivery and the mail deliverer sat in the truck ten minutes then left not leaving a package saying she went to the door but did not since I was watching my package is perishable this is not good for long time customers


Ring Ring Ring, they NEVER and I mean NEVER answer the phone.. Tried Suisun and theirs just disconnects you after 1 ring.. Gotta love Government. What a complete waste of BILLIONS of Tax payer dollars just to deliver junk mail.. More government please....


No answer at Fairfield, ca post office. They NEVER answer their phone.


Tired of no one answering phone plus not picking up out going mail one fillipino says they dont gotta pick up mail if theres nothing comming to residents bs
• Replied to No redelivery of mail


This is not a review, but a question re: the USPS policy/procedure re: government mail. Does USPS forward government mail such as jury summonses or Court notices?


Just spent ringing Fairfield USPS to report poor service on delivery, only to get timed out, because no one would answer. Missed mail delivery at least twice this last week and only got our neighbor's mail today. Sometimes our mail arrives in the dark before six. Years ago ,we were told by a supervisor, that no routes run that late.


I turned in Change of address forms (2) on 9/14/16 from 94533 to 32536 and have not received any of my bills - where is our mail? No one will answer the phone numbers listed - What can we do? A. Blaker See form for phone number


Does anybody answer their phone? ive called multiple times to make an appointment for a passport and nobody pick up, there has to be a better way to make an appointmemt this is ridiculous.


I have had post office box 519 for a very long time.I had a stroke in may and spen a long time in the hospital. I am hoem now trying to recover. I would like to keep the box but cannot drive or walk their yet Lenny DaMassa
