Not happy you say you Delivered a package to my house and I didn't get it ????? tracking # 9361289693090257820814


This office is a joke they do not answer their phones. They caused damage to our property and then wNt us to fix it and then they stopped delievering the mail.


I have several packages on my front porch that ARE NOT MINE! No one a USPS will answer a phone to help get these packages delivered to the correct address


Employees are friendly here. It is pretty busy in there every time I go there.


I see from the comments below that my letter was not the only one delivered to a Longmont address. I mailed it on the 9th of October from the Air Force Acedemy Post Office at the Air Force Acedemy in Colorado Springs. They told me to contact you. There was a birthday check included in the letter. I am very suspicious about the mail disappearing. We had to cancel the check which cost us 30 dollars. It is now the 25th of October and there was no delivery yet. I think there may be a theft going on. Please advise...


I sent mail to my student loan people. They said they never got my letter. I sent 2 other letters and my student loan agency stated they did not revive my mail. I finally faxed my information to them. Now it's happened again! I sent out TWO very important letters out to the STATE they have informed me they NEVER RECEIVED MY MAIL! Who has my mail? WTF is going on?


Inefficiency deluxe! We are asked to make an appointment to renew a passport, and when you call the local post office telephone number, it rings and rings and then hangs up on you. I then called the main U.S. phone number, waited through various computerized phone steps, and only gained the number of the local post office...vicious cycle. Inefficient and very frustrating. Online does not help--only sends you to links of outside providers who charge significantly for passport renewal. This shouldn't be allowed from a government website. Wonder what would happen if this were my workplace, and we operated this way? Get it together USPS!!!


Typical government union bureaucracy: We live in a gated community and the mailman won't come through our gate to deliver packages. Instead, he leaves us a note to pick up at the post office. I have complained many times to the supervisor about the laziness of our mailman and the excuse is ridiculous. He doesn't have to if he doesn't want to, is what supervisor says. Or even better--somebody might have a dog. So at least once a week, I have to make the 20 minute drive to the post office to wait in line 20 minutes to pick up a package that could have been delivered to my home in 30 seconds. Explain how this makes any sense!


Do not use longmont USPS thats located at 201 Coffman St. They've lost my package $400 watch in there, now they blame it on me for not having the insurance on it. Supervisor Jim needs to be fired.


There is also a post office branch located inside the Ace Hardware store on Maine Street, Longmont, but it is not listed.


I live on the block of Sherman Ct. WE have not seen a mailman or received mail in close to a week. WE haven't seen anyone on the block delivering to other houses either so I'm pretty sure it's not that we are not getting sent mail, plus we always tend to get a few daily coupons and such


We are not recieving all our mail or deliveries because of Fredrick / Firestone zip codes and two streets with the same name (Shenandoah), both in Frederick and Firestone. Why is this a problem?
