    I moved away from this area a few months ago. I never knew just how bad a local post office can be until I left Duncan. My new post office is nice and always helpful. My mail isnt opened and searched before its delivered. Someone needs to look into this location. Major change is needed.

    Came here to simply drop off an eBay package. I created the label on Saturday so that I’d be ready to run a quick errand to drop it off on Monday. The clerk denied the drop off and said it was a “stale” label. It was 2 days old. I drove to the Wellford post office and was able to drop it off, no questions. I’ve done this countless times in the past with other packages where the labels have been even “older” and never been denied a drop off. Long story short: skip this location and use the Wellford location if at all possible.

    Continuously receiving mail for my neighbors and missing my mail. I can’t get any help on the phone so I have to go down there. I’ve already complained multiple times about this.
