Where does my mail go? It's picked up but not delivered. Happens a lot. Where is the lost mail? Why can't my loved ones receive a get-well card or birthday card? Are they being stolen?


Horrible service my mail is always going to my neighbors house I'm always getting mail from a business that has the same number but few blocks off on the street and yesterday I received a package in my mail that was to be delivered to west Virginia I live in Oklahoma...... These carriers just don't care at all as last ng as a letter is put into a box thats all that matters to them.... And to never deliver anything larger then the mailbox anymore..... Either they have just gotten super lazy or I guess they need to give heads up to all businesses that we are the USPS and we only deliver letters as long as it's sunny out..... Awful mail carriers


I'm tired of the relief driver delivering my packages to my neighbor across the street. I have lived at my address for almost 3 years. Ask if your unsure about the address, or find another route.


I don't mind occasionally getting the wrong mail but 3 times in 2 weeks and then i try to put it back in the mailbox with the flag up and it doesn't get picked up. Not my job


Sick and tired of receiving tracking notices for package deliveries that don't come as announced. Wait for a package, mail delivered, but NO PACKAGE. 2 or 3 hours later see another tracking update saying "delivery was attempted but not made. Note was left". IT DIDN'T HAPPEN! Maybe somewhere, but not at my address! This happens quite often! Then I don't know where the package will be! I live outside Comanche so the mail comes out of Duncan instead of the Comanche Office. The package may go to Comanche or it may go back to Duncan! This is a ridiculous situation!


Very disappointed with the Duncan postal service. I've put multiple (20) envelopes of stuff in my mail box to get mailed off a couple times and never once have them taken it out of my mail box to mail after a couple days I have to take everything to a drop box because my mail man fails to pick anything up.
