Has anyone lost a package or had poor service in the Hoboken, New Jersey Post Office?

You should call the International Inquiry Center at 1-800-222-1811. They can help you file a claim for your item depending on how it was shipped. Some services come with insurance depending on what country is is shipped to. After you call the number and put in the customs number, when it asks if you want to return to the main menu, don't press anything, just wait. It will then ask if you want to speak to an agent. They can help you with investigating the delivery of your international package.
