Said my package was requested to be held at post office by me; it was not. Where is my package? This was noted Friday


Tracking number says package was left on front porch at 10:00 AM today. Who got my package? I did not.


Something going on with postal truck worker today, 3/21/ 2021 in Hackettstown NJ! It stopped by building 52 at Mansfield village three times!! opening an closing the mail box??? and it's Sunday!


I agree with the previous post. Wonder if it’s the same mail carrier that delivers to Wellington Pl. I have the same issue. It’s either finding wet mail on the ground, which cannot not be read from smeared ink (like my friends wedding invitation) or receiving everyone else’s mail or packages from other streets. When I brought the attention to this carrier, he didn’t even apologize. Not only did he have an attitude, he decided never to pick up my outgoing mail; that I’ve left in my mailbox to be sent out. Now I’m forced to drive my mail to the post office. My flag mysteriously disappeared and I don’t doubt for a minute that he ripped it off. I’ve had my neighbors complain about him dropping mail on the snow and driving away. I also had another neighbor claim that she left outgoing pre-labeled packages in her mailbox and saw when he pulled out the packages from her mailbox; he began throwing his fist in the air as looked up to said house. Isn’t it the mail carriers job to carry out such responsibilities without making waves!?


The carrier delivering to rockport road needs to learn how to close the mail box door!! I'm fed up with getting wet mail; having to use my own envelopes to pay bills because the rain has soaked the return envelopes shut! Contents of hand written letters are unreadable because the rain has smeared the ink and in some cases even the return address. I can see that the post office believes in hiring the handicapped but this is ridiculous!! AND that is when he delivers to the correct address!! I get someone elses' mail about once a month!!


Half the time my packages don't arrive and call post office and they say it arrived and give me attitude all the time.
