Apparently, this place takes their phones off the hook so you cannot call in during the afternoon hours. Worst postal delivery service area I've ever experienced in my life. Always having problems with these carriers.


The post office in Dayton is by far the worst I have ever had to deal with. They don't even attempt to deliver packages, they don't close mailboxes, and the entire staff is lazy and extremely rude. I will be filing a formal complaint with the U.S. Post Master General to hopefully resolve the issues mentioned above. I encourage everyone to do the same so that we can fix these issues.


Dayton, Texas has to worst postal service I have ever experienced. The mail carriers are lazy, do not attempt to make deliveries to the house, and leave packages at the post office without an attempt to deliver the package. I have made several complaints to the local post master who never responds.


Everyone in west Woodland Hills needs to file complaints call 1-877-876-2455 US Postal Inspection service and USPS Office of Inspector General 1-888-877-7644 and anyone else you can think of. Call the post office in Dayton every single time there is something wrong with your mail or package delivery if they receive constant complaints they may actually fix the problem and get a carrier that knows numbers and how to read them


we need a new carrier for Woodland Hills Subdivision everyones mail is all over the place plus she is leaving the doors open on all the boxes and it is getting worse.PLease do something so we can all get our mail.


I need my packages to stop being placed on top of my mailbox or on the ground for the neighborhood to see. FedEx and UPS leave the packages by porch, and I've watched the mail person toss my neighbor's package. We once had a good mail person that did right but I've seen many complains on Dayton411 now I know that I'm not the only one now. I do have pictures.
