Kinnelon Area - Service for mail delivery is progressively getting worse. Today, I have lost but mailed from the bank, a personal monthly statement. That means someone has my personal information. Perhaps better training of P.O. personal is needed. I believe its a Federal Offense to tamper with the mail...... Constantly getting neighbors mail.


I am sick and tired of delivering mail that has been left at my house instead of to the neighbors to whom the mail is addressed.


I left a large package at my front door for the carrier to take. He/she dropped off 3 pieces of mail and neglected to take the package I left. I am disabled and unable to get to the post office. I tried calling the number provided but it rang like 10-12 times then disconnected. Tried again same results. Why list you phone number if no one is going to answer.. Very poor customer service.


April, our letter carrier, is excellent. Professional, courteous and friendly. Hope she stays on our route.
