Why is this location continuously closed at 7:30? It makes it impossible when you have a PO Box to retrieve your mail. On several occasions with no rhyme or reason, this location is NOT open on time!


Location 960 Wheeler Rd, Hauppauge,11788 is the worst on holding true to their hours Lobby hours are 07:30 to 17:30 this morning 9/12/2019 it is 08:35 lobby still not open . The quantity of customers Thant I’ve seen trying to get the mail and can’t is sad. Especially when they are paying for the service of an open lobby to access their mail box.


Dear Sirs, i am waiting for a package destination Italy that departed from your facility on 27 March and whose tracking number is UJ001535228US. From that day on, i can't track it anymore. Could you please give me some explanations Sirs? I need it urgently. Thanks so much Sirs.
