Constantly recieved other people's mail, half the time our mail comes opened, packages end up in the wrong place. We get more of other peoples mail than our own. We are on ward rd in hardwick


Yes I put a change of address in the mailbox at 1054 State Highway 94 Blairstown saying that I was going to be moving and my new address is 74 Appleseed Road Sussex county New Jersey ZIP code 07 461 my mail is still going to the old house


just watched driver dig up my lawn once more. she was even looking out the window as she did it. I now have 200 square feet of mud were lawn used to be. I really don't think she has managed to stay on the driveway even once. The main office doesn't even care not even when I told them a package was once thrown from the window to my porch, I mean how lazy can you get?


horrible post office and horrible mail carries, the carrier on heller hill has NO respect for the elderly, the b**** saw my 84 year old father struggle to hobble down a LONG driveway she sees him and puts the mail in the box at the foot of the driveway where its packed with snow and ice! DOES IT HURT TO DO A GOOD DEED AND MEET HIM 1/2 WAY UP THE DRIVEWAY??? b**** THIS IS WHY U GET NO TIPS AT ALL FROM RESIDENTS ON HELLER HILL!


Do not use this post office after 3pm, I just dealt with the most incompetent employee with no customer service skills!!


I have two comments, both about the parking/cars in the parking lot.
1.  The One Way sign is on the Post Office building facing the parking lot but towards  the rear of the building.  For the last couple of years instances of people coming the wrong way through the parking lot from the rear towards Main Street has increased.  I have encountered  out-coming cars about once a month.  There is going to be an accident soon.  The One Way sign needs to be moved or Do Not Enter signs need to be erected at the rear of the parking lot.2.Parking is at a premium at the Blairstown Post Office.  The parking lot is quite small, most people park in front of the post office on both sides of the street.Employees park their cars in the parking spaces in the parking lot.  Wouldn't it be better to park the mail trucks in the customer spots overnight, then after they are loaded up for their mail routes in the early morning they would then open up the customer spaces?
Today, the lot was full, as was spaced in front of the parking Lot.  I saw 2 men exit a truck with a 2 car length flat bed trailer parked in the Post office parking lot.  They went to the Blairstown Inn for lunch or drinks.  The Blairstown Inn is located on the next block behind the post office!This needs to be addresses soon.
