I use Stamps.com and put postage on a box to mail to my daughter. Over $30, I needed it out yesterday to get to her for Easter for my Grandson. My mail was delivered, but the box was left on my porch (along with other outgoing mail) I called the Centereach Post Office this morning. They were no help at all. The woman I spoke to was condescending and just plain nasty. UPS is now part of Stamps.com and I will be using them to ship from now on.

I went into Centereach post office today to find a package that was in Bethpage on April 4th. I spoke with the supervisor whose name I did not get an asked how I would file a claim. She told me she didn't know how to do this and told me to call 1 800 USPS, which obviously does not have enough digits for a phone number. I suspect she didn't want any claim filed or complaint filed with the USPS. But she was not helpful at all.

I was expecting an item from amazon and it was sent via USPS. The tracking number is Tracking ID 9374889691090747799284. Though it says it is delivered in my mail box it is not there. What should I do?

I just would like to share how horrible service is on the 245 Centereach Maill, Centereach NY location. I found out that post lady or man was giving my mail to neighbor across the street on Tudor street. I have had lost checks, tax documents, and been drop from health insurance and lost my tax credit since my kind neighbor was trow away my paper work but in case of health insurance papers as he done even more: he returner is as undelivered, as a result as lost my coverage and tax credit. I believe whoever is responsible for delivering mail in Holbrook road should be held responsible for all this trouble and misery for me by delivering my mail to wrong address. The were extremely important documents. Its been ongoing issue for months we been finding my neighbor mail in our mail box as well but always returning to him, he wasn't that kind for us. I can't believe this could ever happen! that the post man even though was told to stop trowing our mail across the street to different address is getting paid to put mail to wrong mail box. He fail big time his main responsibility at job and believe in this case should be disciplinary fired from a job! I extremely upset still losing countless hours trying straighten up the mess which I have by missing mail. I'm going to fail official complain for your location as well just terrible horrible experience.
