i am not satisfied USPS SService at all,i am not getting or have any information of the package i suppose to receive within last week. to day i called and holding phone more than 15 minutes and no body responded.


I am new to Monmouth Junction, just moved in a couple weeks ago. My first impression of the post office was not great, I'd have to say. I moved in on a Saturday. I just happened to meet the mail carrier for my neighborhood who asked me if I had received the package he had left on my doorstep 3 days ago! I had not! All he had to say was, "Oh shit. I figured someone was moving in soon since I got a package for the address, so I just left it on the door." The first package I received from the monmouth junction post office was left on my doorstep for three days and taken by someone else. I hope they enjoy my gift, because I can not. :-(
