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 It has been replaced by a flower arrangement.


Is this Millsboro USPS phone always busy? Hmmm.


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