Are they not delivering mail today, 3/1/2021, in Liberty? Curious as we normally have our mail by now, 3:45 pm, but nothing yet.


No mail delivery today because of snow. My package didn't get delivered yesterday. When will it be delivered.


We have lived in Liberty, at the same address for 18 years. We have always had the best experience with our mail service. Up until a year ago. Some days NO MAIL IS DELIVERED AT ALL?? I thought this was The Untied States Postal Service??? I thought they were supposed to have hours Monday-Saturday, except holidays?? But now I guess they just deliver the mail whenever they feel like it. I wish I could get away with just doing my job whenever I felt like it!!! Oh wait I would be fired!!! But since they’re union they are safe from being able to not work when they’re supposed to!!! Very concerning, &, unacceptable!!!


Had a package to be delivered to me on June 23. Tracking said delivery attempted at 11:55am, but "Carrier is unable to gain access to front door to deliver the package". This is a lie! I was right by the front door all morning. There is no reason they could not gain access. Very poor service!!!!


How do I get junk mail/Grocery store flyers stopped? Do not want them delivered to my address. Thank you


We had perfect mail delivery until a few months ago and since then a disaster. The mail is delivered anytime between 10.00 and 5.00pm, and sometimes no delivery, such as today. The mail is frequently mixed up with publicity news papers and literally stuffed into the mailbox. A number of letters have gone missing and we get mail from our neighbors. We want our former mailman back [Bernie]


I had a package sent to this P.O and it never got there. Mailed on 9/12 and disappeared from tracking on 9/18. Today 9/21,still not delivered?? It was a valuable guitar. I will never use USPS again


I have lived at 10400 ne 137th st, Liberty mo for 10 + yrs. I have never been so disappointed in the delivery service on Monday-Friday. Our mail person is leaving our mail in home mail boxes that are vacant leaving others mail in my mail box its bad enough we ask the person that owned the vacant house if we could take down the mail box. I put it back in with a big circle around it and they just leave it in the box even with the flag up. She is delivering our neighbors mail to my box they are getting my mail. In the last 5 months I have had 10 different peoples mail in my box. Then I have to go deliver it cause they wont pick it back up and DO THERE JOB.... I have called in and complained 4 times and nothing has been done. All of us on this route have out numbers on the box, This is pure laziness on the postal person and the post office.


I've had a business at 6 Victory Lane, suite 102 in liberty, Missouri for over 5 years. I have never had a delivery problem until the last 5 months. I am missing mail. Since, I work evening there I am not able to catch the postman to see what the problem is. this is very frustrating. Most of the missing mail are checks.


I had a package arrive at this facility early Monday afternoon. So why is it not at my house today (Tuesday)? This post office is terrible. I've seen my postal worker slap a sorry we missed you paper in my mailbox and they didn't try to come to the door
