    Your service is deplorable. Phones go unanswered, packages marked delivered never arrive, and inquiries are met with evasive responses. Outgoing mail takes far too long to process, and front desk staff are utterly unhelpful. Immediate improvements are needed.

    Lately I have been receiving a lot of packages that have already been opened before they get to me. One of these packages contained a credit card which before we received it had already attempted a purchase for Amazon! Awesome government official mail in my name was opened this is a federal offense and if it continues to happen I will make sure that this office gets closed down since I work with the federal government you work for us it is a privileged to have a job it is not your privilege to go through peoples mail.

    A package I shipped out from here was lost at the post office in Des Moines. The team at Sioux Center spent a week to track it down and not only helped to find it, but got it on its way to us. Best post office staff I have ever encountered.
