Always a pleasure to deal with this branch. I mail within the US and internationally and the staff always helps me find the best rate and assist with the international forms. Thank you all!


This place sucks, the people that work here suck and are lazy and very rude!!!! Im sorry you only work half a day and im sure your so much more exhausted than I am after my 10hr day of outside hard labor but it would be nice if someone here gave a damn about all of the people of duncan's mail. I know its just another package to you people but we expect it to be delivered too our homes or in my case business not coming there and picking it up cause your lazy ass cant walk 10 feet or blow your horn so we can come out and get it!!!!!I would fire everyone in this location if I was over it and hire some oeople who actually give a shit!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


This is the worst post office ever! Our mail carrier always tries to lie and say our packages are undelivered due to dogs being loose when I know for a fact that is untrue, she also has the lady at the post office who picks up the phone to lie for her also, when the issue is laziness! She don't want to drive up our drive way , open up her door and lye my package on a walkway. Its very possible, you can drive up to the walkaway open your door and drop it and deliver it. But instead my packages are being undelivered, they don't want to even try, they will just not even put the package in the car.


Maybe it is different where I come from, but back home, when a package is mailed as REGISTERED Mail, some sort of attempt is made to deliver it. Not here, my mail carrier just pulls up to the mailbox and sticks the sorry I missed you card in the box. Doesn't matter that three cars are in the driveway, and five people are at home inside of the house. Not even a horn blow... Just a "Sorry we missed you" card. My question is how could you have missed me when you never made an attempt to see me. Shouldn't it be a "sorry I was too lazy to make the effort" card? And seriously, you would think that after a year of me writing DOES NOT LIVE HERE on the mail we get for the last three residents of this home, someone would have figured out that it may be the wrong address... Again, asking too much, I guess...
