I was home all day today and when the substitute mail person delivered my mail he put in my mailbox a orange tag saying they tried to deliver a package to me but I wasn't home but yet I was I actually heard him talking on his cell phone then I went outside to get my mail and found this form and he NEVER rang my doorbell or knocked on my door and my car was in the driveway so you would think that would have told him someone was home. Now I have to wait for them to try to deliver it tomorrow or go down to the post office to pick up my package... LAZY


It’s unfortunate that I can’t drop my package off when it’s all prepared, paid and within the criteria, pre-labeled and ready to ship every time I come to Keansburg post office. What is the point of getting it ready at home prepaid and ready to ship if we can not drop it off at the counter??


I want to know what I can do to report something, see I got my mail today and my aunt sent me a birthday card with a gift card in it but when I got it today the envelope was open and the gift card was missing. I want to know if I can report this
