There are certain staff at the Post Office that are very rude and haven't the time to find a package or mail . I get my mail delivered but that's if they feel like delivering it my husband and I are have a hard time getting around so this is getting to be a real problem. And I don't appreciate the attitude from them . they


It's 6:20 pm January 24, 2022 and we still don't have our mail . It's late most the time we live on conn road off conn road Columbia falls Montana 59912 Just want to know why it's most of the time.


worthless post office


Our mail carrier is the laziest carrier I have ever seen. One day we had a trailer parked in our driveway and we watched her drive almost to the house. See the trailer, and back out farther than she would have if she had driven to the house, delivered the package, then backed into the neighbors driveway. Today, my husband got notice that his packages were unable to be delivered because there was no access to the porch or the driveway. But she delivered a package yesterday with not problem. I think she didn't want to deliver them because they are heavy. I want this woman to do her job or find another one. I live in Columbia Falls, but work in Kalispell. I don't have time to take off from work to go all the way to CFalls to pick up packages that the carrier was too lazy to deliver to the house. We pay good money to have our packages delivered to the house, they should be delivered!!!!!!! I have been attempting to call the CFalls office and it is busy. I would like a call back on this issue today! 4062619817.


This is the most worthless Post Office in the nation! How can you not deliver mail to your "main" street on Nucleus?! This is terrible for businesses. We CANNOT rely on mail delivery from your PO as a result! You also RETURN TO SENDER all mail addressed to your main street?@! Horrible for business in CFalls!


What are you talking about? If its on main street and so close, then why can't you just run down there and grab your mail, itd take like 10mins. Why wont they deliver on nucleus?
