This is where you pick up signature required mails or packages that was not delivered to the mail-to address for one reason or another. I did follow instructions on the undelivery notice to schedule a redelivery. When it didn't show up after a week, I decided to taking the matter into my own hand. Alas I went to the postal office first, only to find out I was at the wrong place after waiting in line for 30 minutes. The Annex is actually an industrial facility, sharing the same entrance with Miller Supply. You need to ring a bell to summon help. Things went smoothly once a staff showed up. He took my notice, went inside, and came back a few minutes later with my envelope. I complained about waited over a week for requested redelivery, he suggested I file a official complaint on the USPS website. Overall, I was happy to pick up my mail before it's returned to sender.

Don't bother booking an appointment because the young girl at the desk will take walk ins instead of people who have been waiting for an appointment for over a month now. She told us to come back on an hour later which we did, then has the audacity to make us wait another half hour and then gets her manager to inform us that the post office is closed! This was an appointment for a 7 year old kid with two working parents. We do not have two hours to waste. These people will not take your time seriously and give you nothing in compensation, not even another appointment! Absolutely ridiculous!

I read the document I tell her I'm done and she told me I had to wait until she is finished with her other appointments. 1 hour later she calls me in then complains about my handwriting and told me I will be responsible if it gets rejected then I write her a check and she told me to rewrite it. She talks so fast with her poor English I overheard her complaining about everyone she had an appointment with this one lady asked her what she should put in one of the questions and she told her take it home and find someone to help you full it out. Never met anyone this rude. She's a government employee so she couldn't get fired if she tried she expects you to know everything about passport filing and gets irritated when you dont instead of being helpful and at the end she acted like she did you a favor. My taxes are paying for this? Look at all the negative reviews against her I'm reporting her i hope others will too https://postalpro.usps.com/ppro-tools/consumer-affairs.

There used to be two mailboxes! I had to mail an IRS payment today, so I wasn't happy being here to begin with, now I'm wondering whether or not I should have just walked into the post office and delivered it, but because of the apartment housing across the street sometimes the post office parking lot is full. This location used to be called the El Toro post office, but it is the city of Lake Forest now, name changed in I believe the 1980s? So now it's called the US post office only? Unfortunately, the next time that they'll be taking the mail out of the drive through mailbox will be at 5 PM. Hopefully the IRS will receive my letter and payment !

I stopped by this location this afternoon to drop off a package -- a simple, routine errand that…read moreshould have taken five minutes. Instead, I left frustrated and frankly disappointed by the level of service I received. The associate at the counter, Karen, was cold and unwelcoming from the moment I walked up. There was no smile, no greeting, and no effort to make the interaction pleasant. But beyond her demeanor, what really got to me was the lack of basic guidance. She never told me where to write the delivery address on my package -- something that takes two seconds to communicate and is a fundamental part of the job. As a result, I had to redo the labeling entirely, wasting both my time and my packaging. What makes it worse is that this kind of mistake is completely avoidable. A simple heads-up -- "make sure to write the address here" -- would have saved the hassle. Instead, I was left to figure it out on my own and then correct it under her watch, which was both inconvenient and embarrassing. Good customer service doesn't require going above and beyond -- it just requires the basics: a courteous attitude and clear communication. Today, I got neither. I'll be looking for an alternative location or courier going forward. Life is too short to spend it dreading a simple post office run. I'd strongly encourage management to revisit customer service training here, because first impressions -- and last impressions -- matter. Not recommended.
