What ‘s going on at the south main post office in Santa Ana. Mail going to the wrong address & deliverd to wrong street. And NO market add’s, unless I beg for them. Very inconsistent service. A LOT of people here in Whilshire Square are complaining. Some are reporting missing mail & NO mail. The service I am receiving is rated at D-. Please don’t make me rate it at a F.

For 5 days now ( ALL WEEK) my mail has been man handled and shoved into my mailbox! It's crunched up even when there's only 3 letter size envelopes in it. WTF?! My daughter recieved an acceptance letter from a college that was completely wrinkled up. She had planned to keep it in a keepsake folder. I'm so pissed! Who the hell do u have working there?!
