They continue to be closed, both Mon and Tues of this week, neither of which are holidays. They list their hours as M-F 930-5pm, and they have my mail from my hold, including my car registration. It is madness.

On Sunday 12/11/2022, I went to this post office at 10am. It was supposed to open from 10-3pm for lobby area PO Boxes but it was locked. I waited for 45 minutes and finally gave up. So many people dropped by too but eventually gave up. There was no note and the hour sign that use to hang on the lobby door was removed. Is this place going to shut down? How am I to get my mail/packages? Can I get a refund on my 6-month payment for PO Box? I called this post office and no one ever picks up the phone. Does anyone know what is going on? Who can I call or talk to?

Poor pick up and delivery to our block on S. Mary Ave. Lately, our delivery service has been poor, at best. Today I received the mail for my next two neighbors. Delivery person didn't even stop at their houses to pick up outgoing mail like he couldn't be bothered. We sent out 2 letters over a week ago that haven't reached their destinations. We do not want this delivery person on our route any longer as this is an ongoing issue. The Hunt's @ 1473 South Mary Avenue, Sunnyvale CA. 94087
