Carrier stuffed package in the mailbox that was too big for the mailbox. We live on Rte 94, heavy traffic zone. The package was jammed in so hard I couldn’t get it out. And the end of the box was sticking out of the mailbox with the door hanging open. All unacceptable!

I am passed angry. I received a hand written scribble on a piece of paper during a rain storm (rained for the next week) that I needed to raise my mailbox that has been there for over 25 years. So I called the post office and asked why the height is not according to to US postal service numbers and I explained that I was quarantined till this last Monday. I just received a notice that they will no longer deliver my mail. My question where was the official notification that ALL mailboxes needed to be raised to 50inches (5-9 inches taller than US standards) and how long did they know that they were going to get new trucks and could have given us a sufficient amount of time to change our mail boxes. I have always supported the Post office. I am questioning my judgement !. By the way the number listed to call the NEw Windsor Post Office doesn't get you the post office is this because you don't want to talk to anyone

Tracking info says my package was delivered and left in my mailbox. No package! No answer on the phone! No help whatsoever!

What a train wreck of a post office. No joke. Nobody ever answers the phone. Anytime you go in this place you better have 20 minutes of time to waste because the clerks work a snail speed. But at least they are working. 2 or three others just doing nothing off in back while there is a line of 10 people in front. The poorest managed post office I have ever been stuck having to use. Now I have a package that was misdelivered and I have spent an hour on hold after 25 min in an endless voice system only to be on hold again. tried to call directly to the post office and of course nobody answers the phone even worse your voice mail box is not even set up. Talk about a joke. And they wonder why people skip using the post office anymore. Clueless leadership. Feel free to contact me because I would love to tell you about my last experience waiting in line only to have someone who must be a regular come in and cut the line and none of the clerks said jack to him. I did and I was the one who they shook their head at.... you people are worthless.

Terrible mail delivery service !. Worst carrier I ever had .Carrier consistently delivers other people’s mail to my box. She doesn’t pay attention to addresses. I get mail every day and now haven’t had a delivery in 6 days! Where’s my mail? Wonder who s address it got delivered to ....

It seems we have run into a never ending cycle of problems when it comes to the postal office and deliverers of the New Windsor branch. The package delivery is a shameful and horrible process, there was a parcel room created in my apartment complex and the deliverers from USPS REFUSE to use it, and they also refuse to go to the doors to deliver packages, they return them back into their stations and now packages that are needed (for example my medication) are now delayed and I run into problems with them over and over again, no matter who I talk to or who I complain to it seems to go in one ear and out the other. The post office say they are all about efficiency and timing yet the don't achieve it, I mean getting my mail at 6-7pm at night is ridiculous. I have complained and so have others from the complex and yet nothing is being done.

I live in New Windsor NY 12553, and I just witnessed my mail carrier drive right past my mail box, when the flag was up for outgoing mail to be picked up. That is two days in a row. What ever the federal government is paying, it's obviously TOO much!!!
