I check my PO Box 1028, St. Helena, CA daily. Today I received a box of mail as if I had not checked my PO Box. Many were bills that are past due. I do not know why the mail was not put in my box on a regular basis.


I would like to talk to a manager. About one of your mailmen. He seemed a little off today even dropped my mail on the floor and bumped my husband's side mirror as he walked by. And acted like he didn't care when my husband asked him if he was ok.


Do not use this post office, I mailed a simple card from there to rohnert park and it never got there. Thanks alot!!!


Receiving is spelled incorrectly - oops (see Mailbox & Postal Services above)


Maybe I'm blind, but I'm not seeing the word "receiving" anywhere on the page?  Was it maybe in an AD above the "contact numbers" or below the map?
