I've tried to call the phone for days - no one ever picks up - just rings and rings and rings. I've had my mail forwarded temporarily - and it has yet to be delivered. The mix up is on the Mill Valley end, it seems. I'm finding USPS to be very unreliable and unprofessional in general! If they aren't going to pick up, then they shouldn't advertise the option of calling!


The guy in the Mill Valley Post Office who deals with passports is not helpful, pleasant, etc. Very unpleasant process.


I've tried for days to call to get a passport appointment and either it is busy or just rings and rings and nobody ever picks up. Very frustrating.


I have tried for 2 days to get through to someone on the phone. The line has been constantly busy - or no one answers the phone.


Please hang up your phone. I have an important message and your line is always busy!
