I'm just confused as to why my packaged was not delivered and was updated as "access was blocked" when there was nothing blocking access, there were several people on site that could have received the package including myself, and on top of that we still got our mail delivered.. SMH for real


Not only is package late ,driver stated they attempted to deliver and didn't do so but was also dishonest about attemp time. When I tried to call sonora branch no one seems willing or able to answer the phone


Never yet has Package shipped as expedited package arrived within promised parameters. Delivery to my house as promised and claimed by USPS to my door has never occurred . Packages routinely are lost , damaged and at best late. Never have I received any pkg on time for 2yr


Dreadful service. Lost packages (three times in 6 months). Undelivered packages for no reason other than not wanting to drive down a dirt road (unpaved but in good condition) for 500 yards to deliver to house. No notices left in mailbox. Post office can't find the packages even though they have records of them arriving. No apologies for anything. Just a shrug from the supervisor.


I have several complaints concerning my mail delivery for the past few months it has been terrible! 1. mail doesn't arrive until between 4p.m.-8p.m 2. mail sent in my mail box, taken by the mail person, is lost, this has happened several times 3. mail received is lost,also happened several times, when the computer says it's been delivered to my address 4. when pkgs. are delivered to my home,the mail is not included with it. PLEASE HELP!!!


Never had problems picking up my Social Security check in the morning before until today when I am told not until 12:30 p.m. Highly irritating when Social Security Checks arrive at least 1 day prior to delivery. And my gripe is with one individual who has been at the register, at the door to pick up packages and mail, and now on telephone. Now I have to sit here and wait 3 more hours. She is rude. When I get her name I will return with the name.


I am unable to reach anyone at my local branch in Sonora regarding a ruined piece of artwork for a shop. I've got photographs of the damage done, it made it to buyer but part of it was torn and taken, and the mailing tube was sawed through and then retaped. It's beyond heinous to do this, and it hurts my business (and livelihood). This post office has surly, rude and downright disrespectful and unhelpful employees. I cannot understand why and how this could have happened.


PO box access hours are posted open 24 hours. But at 7am the doors were locked. Great customer service Sonora USPS.
