    How about actually delivering parcels instead of falsely marking them as no access to delivery location

    I have had repeated issues with mail and package delivery at this location. Packages are consistently delivered incorrectly, misplaced, or marked as delivered when they have not actually been received and they will turn up days later. On one occasion, I received a package belonging to a neighbor that contained eye medication she urgently needed due to her vision problems. Receiving someone else’s medication was extremely concerning, particularly given the potential consequences if it had not been promptly identified and returned to her. I have also had concerning experiences with the staff at the postal office. On two separate occasions, staff members allowed me to pick up mail without checking my identification. This raises serious concerns regarding the security and proper handling of customers’ mail. Additionally, I have found the customer service at this location to be consistently rude and unhelpful when addressing these issues. The repeated delivery problems, along with the concerns regarding identification procedures and customer service, have significantly undermined my confidence in the handling of my mail.

    I am beyond frustrated with this post office and the mail delivery service in my neighborhood. The mail carrier assigned to my area repeatedly misdelivers mail—almost every single day. I have received other people’s mail in my mailbox, and my own mail has been delivered to the wrong addresses. This is not an occasional mistake anymore. It is an ongoing problem that needs to be addressed. The most serious issue happened when I saw a check addressed to me listed in USPS Informed Delivery. The system showed an image of the check, confirming that it was supposed to be delivered to me. However, the check never arrived. Because the Informed Delivery image does not provide enough information about the sender or return address, I have no way of knowing who sent it or how to get it replaced. If that check was delivered to someone else’s mailbox, that is a serious failure involving someone else’s private financial mail. What makes this even more frustrating is that Informed Delivery has also shown me images of mail belonging to other people in my neighborhood. I should not be receiving previews of other residents’ mail, and other residents should not have to worry about their mail being mishandled or sent to the wrong address. At this point, I am sick and tired of having to deal with this. I should not have to wonder every day whether my mail is going to arrive, whether my bills and checks are being delivered correctly, or whether my personal mail is ending up in someone else’s mailbox. USPS needs to investigate this carrier, address these repeated delivery errors, and take responsibility for fixing this situation. This level of service is completely unacceptable. And the last thing I want to address is the supervisors, postmasters, and management at this location. What are they actually doing to correct these repeated issues? It feels like they let this mail carrier do whatever he wants, with no accountability and no consequences. I have had enough of reporting problems and seeing nothing change. Management needs to stop ignoring this and start taking responsibility for the service they are providing. I should not have to worry every day about whether my mail is going to the right person, whether my checks are going to disappear, or whether I am going to receive somebody else’s private mail. This situation is ridiculous, and I am demanding that USPS investigate this carrier, review the repeated misdeliveries, and take real action to fix the problem. I am sick and tired of this. Enough is enough. If you live at the THE MET Apartments in Riverside and you missing mail most likely it’s in my mailbox cause I got about like 40 different neighbors mail coming into my mailbox And my mouth is probably going in everybody else’s mailbox. My mail probably has ended up in 1000 different mailboxes.

    I am extremely disappointed with the customer service I received at this USPS location today at approximately 11:40 AM. A few days ago, someone vandalized the community mailboxes in our HOA. USPS posted an official notice at the mailboxes informing homeowners that our mail was available for pickup at this Post Office location at 4150 Chicago Ave., Riverside, CA 92507. The notice specifically instructed us that we did not need to wait in the regular customer line and could instead go directly to the blue “Dutch” door, where an employee would retrieve our mail. I followed those instructions. When I arrived, I first went directly to the blue “Dutch” door identified in the USPS notice and attempted to get assistance. No one answered the door. Since I could not get assistance there, I then got into the regular customer line so that I could speak with a clerk. When I reached the clerk working at the counter nearest the Passport Office door, I explained the situation and asked for my mail. She told me there was no mail for me and claimed she could not find any information indicating that homeowners from our community had been instructed to pick up their mail at this location. I had a copy of the USPS notice with me and offered to show it to her. To my surprise, she told me she had no interest in seeing the notice and that it did not concern her. Instead, she told me to visit the USPS website to find out what was going on. This was incredibly disappointing and dismissive. I had followed the instructions USPS provided. I went to the designated door first, received no response, and then waited in the regular customer line specifically because I needed assistance. The very least I expected was for a USPS employee to look at the USPS notice I was attempting to show her. I then told the clerk that rather than going to the website, I would email Andy Valdez, whose name appears on the notice as Manager Customer Service, to find out what was happening. Only after I mentioned his name did she tell me to wait while she checked something else. A few minutes later, she returned with my mail. She then told me that the postal carrier had apparently failed to label the mail correctly. Mistakes happen, and I understand that. What I do not understand is why she was initially prepared to send me away without my mail and without making a reasonable effort to investigate the situation. My mail was there the entire time. I drove approximately 20 minutes each way because USPS specifically instructed me to come to this location to retrieve my mail. Had I simply accepted this clerk’s initial response and gone home to check the USPS website, I would have wasted a 40-minute round trip and still would not have had my mail. What makes this particularly frustrating is that the attached USPS notice clearly states that our mail “is available for pickup” at this location and that an employee would retrieve it for us. Yet the clerk initially would not even look at that notice. USPS needs to do a better job of monitoring the customer service provided by its staff and properly training employees who interact with the public. When a customer presents an official USPS notice and asks for assistance, an employee should at minimum be willing to review the notice and make a reasonable effort to help rather than dismissing the customer and directing them to a website. I have attached a photo of the actual USPS notice for reference so that others can see the instructions we were given. I have redacted Andy Valdez’s USPS email address from the photograph out of respect for his privacy. Other than that redaction, the notice is shown as it was provided to our community. This experience was extremely disappointing, and I hope USPS management reviews what occurred and provides appropriate customer-service training so other customers are not treated this way.
