I just called to speak with a "human" and just keep getting the runaround loop of operators not available it would be nice for the recording to say ...leave a message and we will return your call as soon as we open our hours are…or whatever the issue is..

How does one make an appointment for Passports if nobody at this post office or any other post office within Fairifield answers the phone. It also says to leave a message and then the mailbox is full. Very frustrating!
