absolutely horrible! Whenever I order a package that won't fit in my mailbox they drive away without leaving it at my front door when I went out today the mail woman wouldn't speak to me when I said wait got two out of six envelopes in the box and didn't close the door. Also without my package I've been waiting for so I called the post office and before I could finish what happen the woman said oh my and hung up I am very very disappointed that now I'll have to maybe wait longer to receive my package
