They do not answer the phone… i CALLED A DOZEN TIMES!!! I RATE THEM A ZERO…0


This post office must have been rejected by the US Postmaster General. God forbid you try to call them I believe they pay one person just to pick up and hang up the phone because they never answer it. If you have a question for them or need assistant don't ask an employee because they will totally ignore you. When you get tired of having your mail thrown over your fence you might want to contact the US Postmaster General or if they put a orange label saying they tried to deliver and you sat right there as you watched him fill it out you know that they hire Liars so who's to say they're not ex-cons. With the informed mail they're the ones that put it in to send us the email showing us within our mail and God forbid if it's addressed to somebody else and they put it in you'll never get them to take it back it'll never get to the person it's addressed to because they will not take mail out of the mailbox even if you put Return to sender and clip it outside your mailbox it will sit there until the sun deteriorates the envelope that it's in and it is shredded beyond recognition. The people do not know how to speak to other patrons nor do they know how to assist other patrons they say they don't get paid to do that it doesn't fall under the postal code are you freaking kidding me? If you're a moron and proudly admit it this place has a job for you because you have to do nothing you don't have to know anything you don't have to help anyone and you still get paid just for showing up that's a pretty good living if you ask me plus it's government so what does that tell you about our government ? Tells me even Kamala Harris couldn't do this job. Agenda of the postal employees to do anything else I don't believe they can even color within the lines.


USPS IS INCOMPETENT! It’s been 16 days on this Priority package! With no damn updates or help from anyone. I will never ship with you morons ever again! 9505816931010335007996 David L. Coslow
