I subscribe to Food Network Magazine and have had for years. This year is proving to be a problem ... So far there have been 5 issues of which I have only received in the mail 2. I have called to complain but was told magazines were not a high priority. I have complained to the publisher who claims it is being sent out. Something is wrong and I am very upset over this.


Every Saturday I get a message from usps that a delivery was attempted. Message says Doors were blocked or driveway was inaccessible. You could drive a 18 wheeler up my drive way and turn around. I have three doors that can always be accessed. Every other carrier finds my house and delivers my packages. I would pay extra to have any other carrier deliver my packages..........wharton n.j


I need to reach someone from the Dover Post Office about delivery of the mail at the small apartment complex I manage in Wharton. I've tried several times via phone and either I get no answer, or am put on hold for a long time and no one picks up. Please contact me as soon as possible so I can verify my mailing information. Thank you!


1. My mail has been repeatedly returned to sender when the address is clearly correct. 2. I frequently get my neighbor's mail in my box. 3. Today, my package was left in a snowbank under a dripping tree branch and was found completely soaked. My covered porch is the same distance from the street. 4. The Dover Annex NEVER answers the phone. One cannot imagine worse service within the USPS. It's a disgrace to a once highly regarded institution.


I live in Randolph. Frequently we have neighbors mail put into our box. Yesterday all of the mail, 5 items, belonged to our neighbor. I put it into their box, which also contained correctly delivered mail. Who knows where our mail may be? If the mail can be delivered on a snowy day like yesterday, why can’t it be delivered correctly? I also called the Dover annex. The phone rang and rang and no one could bother to answer. Eventually the call was interrupted, which probably required human action at the annex. Do you understand why taxpayers have no respect for your service?


I want to complain about the carrier for my home in Wharton. She stood at the top of the hill and threw my package (an Amazon package) onto my porch. This package contains electronic items. How lazy can she get. I will also be contacting amazon to let them know how poor your service is.
