    Awful customer service. Rude, no courtesy, and they really seem to dislike even being there.

    The worst USPS location ever. I always have a problem with this USPS whenever I am waiting for a package to be delivered to my house.

    I scheduled an appointment online for a passport application for today last week and when i arrived…read more20 minutes before my scheduled time, there was someone else who said they've been waiting for over 30 minutes and also stopped by the day before to find out the passport office was closed. When I asked an employee for help, they explained that the office is closed because management doesn't want to pay for overtime so they closed early. The employee asked if I can come by the next day before 3pm and I responded with saying "no, because I work and I requested time off to be here. Which is why I also scheduled an appointment online. If you guys are going to close, then you should let people know." She responded with saying to call the numbers on the passport office to complain. I took photos of the phone numbers and everything else taped on the office doors. Both numbers listed do not work - they just keep ringing. It's pretty ridiculous if you schedule online for specific time and you cannot be helped by anyone.

    Located on the corner of Susan St and Sunflower (catty corner of the IKEA off the 405 Fwy). This…read moreISPS location is my favorite location. Since it's the distribution center, they're open MUCH later than the typical post office. Their full service hours are Mon-Fri 7a-7p, Sat 8:30a-3p! I've always had great service here even when I was running in from the parking lot hoping to make it through the doors before they locked them. Even one time, although the door was locked, and the gentleman was standing there, he allowed me to pass him my stamped mail so it could go out that day. Like I said, the service has always been great here! I also love this location because they have self service machines inside the building and the doors are open 24/7. Tonight, even the general nighttime manager saw me at the machine and dropped died to chat. He was so sweet and friendly. The clerks here are always great too. Never had an issue by the way the postcard stamps are $.61 each. How I miss those days when they were $.15 each lol I guess the value is still good if you consider everything else has been inflated. I still highly recommend this USPS location for all your mailing needs..

    I was there last week when a wondeful lady was working, Elaine Terry. Apparently she rotates…read morebranches, so she's there only some of the time. She was fun, cheerful, efficient, and awesome! She joked alittle, and I loved it. I wish all the tellers knew their stuff like her, and made the atmosphere more enjoyable. An older lady got really cranky/upset with her and I watched the whole thing play out. IMO, the customer seemed dead set on being a hater of this employee. Anyhow, if only all employees could be more like Elaine, I'd enjoy waiting in line and coming in more! (We had a package we missed delivery on, so had to come get it.) Thanks Elaine for being efficient and a ray of fun sunshine. I took a photo so if you see her there and say hi if you see her. Hopefully you too leave alittle happier than when you came in.

    I went to the Santa Ana Post Office at approximately 4:40 p.m., before their posted closing time of…read more5:00 p.m. There were only two employees working at the counter: a man and a woman wearing a red vest. I picked up a form and politely asked the woman if it was the correct form for an international shipment. Instead of responding professionally, she loudly stated, "We don't do them at this time," in a way that everyone in the lobby could hear. She did not apologize or offer any assistance. She then said there were only 10 minutes left until closing, even though it was still before 5:00 p.m. and there were only five people ahead of me in line. A few minutes later, she again announced that they do not process international shipments near closing time, claiming that it takes more than five minutes. She then went to lock the side door and came back to me while I was still waiting in line. She repeated that they would not process my international shipment because they were about to close. I told her that I had already heard her say that multiple times and that I simply needed to pay for the envelope. She continued to insist that I did not need to pay for the envelope instead of addressing my concerns or offering any solution. What was most frustrating was that after 5:00 p.m., several additional customers were still allowed to enter the post office. In fact, as I was leaving, four more people walked in, and there was a line extending out the door. I do not understand why I was refused service for an international shipment when I arrived before closing and other customers were still being allowed into the building. I found the employee's tone and behavior unprofessional, dismissive, and unnecessarily rude. I believe customers who arrive before closing should be treated respectfully and provided with clear, courteous explanations regarding any service limitations.

I've shipped packages in reusable bags for over 2 years. I work for ups and understand customer is not the easiest job but you aren't obligated to stay there. I have a feeling she's going to make sure my packages get sent back to me because of how bitter she was. If I were you avoid this place at all cost go to the fountain valley location wayyy better

That should tell you how welcome the public is at this facility. The few times I've had to visit this location I've been the ONLY customer in there and I've never had a pleasant experience. Today was no different. I asked if they had certain stamps and the woman behind the counter acted as if I had just asked her the dumbest question on the planet. How dare I assume the post office would have stamps, that the post office produces....to actually sell to me??? Then I handed her the prepaid/preposted box I was there to drop off and she had the audacity to ask me what was inside the box. What in the actual heck is that about? My mailman doesn't ask me what's inside a box when I schedule a pick up from my house and the drop off area at the Sunflower post office isn't even manned so they aren't asking anyone what's in the boxes they're dropping off. I truly don't understand why the woman who works at this post office is so miserable and petulant. She should work in back and not be up front because customer service is NOT in her skillset.

There were maybe 5 people ahead of me. I was able to be in and out in about 30 minutes. Around 2:25 PM, people were crowding inside. One booth was partially reserved only for passports. I decided to come here since most locations are either closed on Saturdays or have very reduced hours. I even visited a tiny USPS in Whittier recently that felt super deserted. The downsides are the fact that it is stinky inside (old people funk), and the person behind me got so close as if she was trying to cut the line. But glad I found this place, as it was pretty much the only option for me, due to the availability of hours. My COA was pending and got denied. The employee let me get back in line 3 times, however. I had to fill out a form in person, since the online application was timed out. Hopefully, the system sorts my mail correctly, since the e-mail they sent was extremely insightful. Employees are very kind, and apologized to customers for the wait. They also have ratings for service. FYI: It seems they are also out of tape today. Also, it was really confusing to exit the parking lot since I think they're only three ways to go out and I believe two lead you through residential alleyways.
