Called to find out what time they closed today, tax day. Not staying open any later. Elizabeth used to stay open until midnight on tax day. She did not know of any offices open any later. Down town Newark may be open but not sure. Really? You work there, should have this information. Tax Day. No one tells them this? Nonsense...


scheduled a pickup online last night. explicit instructions where it is, on porch, inside door on the floor to the left. never picked up, but 5 deliveries made. last one put the delivery on top of the pickup....a holes. no wonder they are losing business to ups and fed ex. they blow


I see that the parking lot at the post office on West Chestnut St. is still closed for repaving after more than a month. I need my driveway repaved. Can you please let me know who the paving contractor is so I don't make the mistake of hiring them?


On July 25, 2017, I called the 1130 W Chestnut St, Union, NJ 07083 usps location at 4:50PM to check on a package that I'm worried about. Whoever was working that day decided it would be cute to pick up the phone, put me on hold and then leave me on hold until the location closed. I just had a simple question, but I got treated like dog shit just because it was close to the end of the day. I don't appreciate that.
