What the heck is going on with the crummy Postal service or lack there of in Seabrook, NH. They put mail in our box a month after we moved with a correct forwarding Address instructions handed to the office workers twice. Called wit NO answer during “open” hours No wonder they got Covid because the workers behind the desk were NOT wearing masks and neither were many customers who waited in line crowding together . Sorry they got sick but those who defy scientific advice to wear masks are spreading their death germs to others!! Merry Christmas. Maybe we’ll get out mail delivered to the correct address by Easter ! Happy New Year

Just got off the phone with a postal worker at the Seabrook location. The only comment I have to make is that whoever this man was, needs to work on his phone etiquette skills. I remember saying “thank you” and the guy slammed down the phone without saying a word. Rude. I don’t care who you are or where you work, if you are the first point of contact for a business, you represent that business respectfully.

Can someone please tell me why my social security check wasn't in my mailbox on Fri. when the 1st is on Sunday? Didn't come today either. This is not the first time this has happened and I know that it's the post office and not social security office. Are they that lazy?

This is the worst post office ever. They constantly refuse to scan labels when you drop off packages for shipping, so your buyers then complain cause they can't track their packages. They are ruining my online business. So now I drive to the next town to ship my packages, all I want is for them to do their job. USPS in Seabrook NH SUCKS!!!

Have you tried doing the shipping at home on a computer? It is so much easier and cheaper. And the bonus is you have the tracking number right there. Good luck.
