Buffalo Junction Post Office in Buffalo Junction, VA review: Mail service

I have filed a complaint in the past about the person who delivers my mail and will not close my mailbox. I came home from work and it has rained all day today. My newspaper was soaking wet all because the person refuses to push the door shut on my mailbox. Is there any way that I can change who delivers my mail? I have spoken to others in the neighborhood and they have the same concerns and most of them are elderly. Please let me know what I need to do to make sure that my lid is shut so I do not get wet mail or mail is laying on the ground.

Thank you!
