Postal Locations

Question If I had a complain or question to this post office in Montebello, where can I direct it, because I try to call about 20 times and the call didn't go thru, this is something that I really need to share with the post office, please reply where could I sent a complain or how could I talk to someone, it is kind of urgent.

I’ve been home all day waiting for my package, but yet they say they couldn’t get access?!? I am always having problems with receiving my packages? They are so unreliable!!

Awful no answer at all at this location! Mail lost stolen or ??? No one will answer the phone at this location! Very poor cs!

My original mailbox, installed in 1951, was moved to the sidewalk years ago due to dogs on the premises. I have lived here, 828 S. 4th. St., since 1987. I don't have dogs, I have fibromyalgia, I am 67 years old, important mail has been missing, the mail was left at either box, etc. I adviced the supervisor in turn at the Montebello Post Office, months ago, that I was going to take down the mailbox. . . she said no problem. . . asked me for my phone number to give it to the carrier. My mail is not being delivered. I have retrieved it from the PO numerous times. Please tell me what to do. . . Respectfully, Irma Franco

Hello everyone, I sent a package to my sister a care package for her, my mother asked me to send her letters she told me those were for her and I told my mother I put all the letters in the box and she told me some of the letters weren't for my sister, so what can I do to get the package back send the letters to the proper places they are supposed to be sent, and resend the package.
And I sent it today in 9/12/14
