Our mail deliverer left my mail on our doorstep with a package in the pouring down rain. When I picked up the mail water was pouring off of it. I have called about this problem before, but they don't seem to care


Where is my mail ? I have not received my electric bill, my capital one, my bank of America bill or Bj,'s. Will the post office pay my late charges? This is insane worse service ever. Please respond.


I have 3 packages said delivered between Monday and Thursday. None are in my my mailbox


I have called the post office twice this week about a package i never received from my aunt. I spoke to two ladies who stated they would get back with me and never did. I am so frustrated about the communication and the post office attitude to not even give a call as they looked into it.


Mailed two large checks from Oak Meadows, zip 19966 to Lakeland Florida Beginning of November around 7th and 2 days later I mailed 50.00 cash, because I ran out of checks, to my grandson who is at Indiana University in Bloomington, Indiana. He never received anything in the mail. I even put the card in upside down so you would have to take the whole card out to take the cash, Well it's gone!!!! THIS IS A DISGRACE!!! NOWONDER THE POST OFFICE'S REPUTATION IS GONE TO THE DEVIL!! THESE CARRIERS OR WHOEVER ELSE HAS ACCESS TO THE MAILED MAIL IS STEALING!!!!


This place has me so fed up. Today would make the 5th time in last 5 months that they have “lost” my package after tracking data says it was delivered to my mailbox. I have ZERO problem getting packages from any other carrier nor ever had a problem with someone tampering with packages. The manager.... if you are lucky enough to get ahold of her...says she will look into it yet never hear from her again. It seems like the carriers are stealing. One package was even delivered with the contents stolen. I don’t even know who else to contact at this point!


I am agreeing about how difficulty it is to reach this PO - the phone is always busy, and I just called the 800 number, hoping to be transferred, the wait time is 48 MINUTES! What the heck is the problem here?


Their phone is ALWAYS busy, they obviously take it off the hook, probably because they don't want to answer to the customers whose package they lost. Like mine.


what is with this post office delivering your packages to the wrong place every time I send off to get something mailed to me it goes to the wrong house or where ever they put it getting very mad.


I was in the Millsboro post office this morning and noticed there is no picture of the President in the lobby. Previously, for the past 8 years, a picture of President Obama was there. It has been replaced by a flower arrangement.


GOOD, who wants to look at TRUMP"s face. He is a disgrace to our country.
• Replied to President's Photo


Is this Millsboro USPS phone always busy? Hmmm.


all I can say is go to the BBB and file a complaint
