We are missing a package that was marked delivered in box at 7:58pm on Dec 2 and there wasn't anything there when we got home that evening around 8:30pm. Asked all neighbors they didn't receive it. Very upset. Our postal service has been amazing for the past 3 years since we moved here until the past month or so.Usually delivered no later than 12 noon now it might come around 6-7pm.need help finding my missing package that was actually NOT delivered but marked it was.

They need to hire a new passport agent! I was called the day of my son’s passport appointment asking if I could come earlier because the agent had to leave. She said I needed to get there before 11. I got there at 10:45 because I had to go to cvs to get my son’s picture taken. When I got there the guy upfront told me she was gone for the day. They need to purchase a new camera for the passports anyway. It’s never working and people always have to go to cvs to get their photo taken. I have issues every time I have to bring one of my children to go their passport done. This is really ridiculous.

Yesterday i had 2 packages delivered. One was a 8lb sledge hammer. The mail lady that we have in Barnwell decided to drive her mail truck on our dirt that we have grass seed on and make all kinds of tire tracks and must have sank. We had to get put in new pipes a month ago so that was why we had dirt there and grass seed. You can see all kinds of tire marks in it. My husband called the Barnwell post office and was told basically too bad. I took all kinds of pictures and will be calling Customer Service to see what we can do
