According to a delivery notice dated 6/12/17 for a package which needed a signature, the delivery mail person said that they attempted to deliver a package. However, that is a lie! I work at home and I was at home all day. My door bell even works. The problem with the mail system is that it is all Union and nothing will happen or be said to the delivery person. I had to make an extra trip to pick up the package. So, I wanted to file a complain that the delivery person is a lied. After they had me wait and then tell me the manager was on the telephone, which I do not believe because the counter person when back and was talking to a man which probably was a supervisor who was not on the telephone, I left. I must say, generally the deliveries are good. I have received someone's mail in the past but not recently. I hope episode is not a prediction of what future mail deliveries will be like.


They deliberately alter my address and send my mail back as unverified. They have caused me more grief than i can describe. I took the evidence of altered address directly to them and laid it on the counter...he lied to my face despite the obvious and willful alteration..and would not give me the name of the lazy employee who would rather alter my address and return my mail...than actually do his job. They take the phone off the hook in the afternoon from 3pm to 5pm. Even other post offices can't talk to them. They all deserve to be fired first, arrested next.


The post "man" for 08094 on Main Street in Williamstown, NJ I COMPLETELY INCOMPETENT!!!!!!!!


Hello, I am writing to complain about not receiving mail for today, (which is not quite over yet) 3:30pm, and the other day, which there was no mail on my street at all. Mail usually comes by now so I am just figuring he/she is not coming today like the other day. I am a stay at home mom and do a lot of online shopping. Tracking says my package is with the carrier but there is no carrier. What's up with that?


Absolutely the worst post office ever. I've called 7 times about a lost package two people hung up on me. Another person never called me back and still haven't found my package.


mail people needs to stop driving fast in people driveways


mail people needs to drive slow

I went into the post office on a Friday afternoon around 4pm. I approched a lady working there with short brown hair and glasses. I had a few boxes to mail that were not labeled. I continued to ask her for help because I was new to printing out my own lables and shipping them, She gave me such a hard time and continued to roll her eyes at me asking me if I sell online I should know what i'm doing. How rude is that? Lady, I get it, it's 4pm on a Friday and you want to get out of work, but that does not give you the right to belittle your customers. She did not help me with anything at all. In fact a guy named Jim was really nice to me. The lady was not wearing a name tag and if she was wearing one I would report her. I hope to never expierence anything like that again there. If anyone knows her name please comment!


Today I had a knock on the door from a USPS package delivery truck driver who wanted to make sure no little ones were around because the toy being delivered was easily identified by the packaging. She then went back to the truck to retrieve the package.How thoughtful was that? Really puts you in the Christmas spirit when someone goes above and beyond what is expected.
