This is one of the worst postal services I’ve ever had to deal with. We are constantly getting the neighbors mail and bills and packages and I’m sure they’re getting ours apparently being able to read is not a qualification of the US PS I would like the postmaster to call me back for Mount Vernon USPS my phone number is 812-893-9443 which I did call their office at 4 o’clock in the afternoon which says they’re closed and they’re not supposed be closed until 430


Trying to set up a hold mail request on-line, but keep getting message can’t do so due to a current hold mail request in effect. I have no current hold mail request in force. How can this get corrected and updated?


i am trying to figure out where my package is. the tracking number is RH515013208IN. it says that the package is "DELIVERED TO AGENT FOR FINAL DELIVERY MOUNT VERNON, IN 47620" on Sep 4, 2021. That was 6 days ago and it still has not been delivered. Please advise.
