Package was supposedly placed in mailbox on the 10 th, these boxes need a key to open. Was away when I opened box no package, either it was never delivered and Carrie said it was, carrier kept package or was placed in someone else’s box. Was a for a Christmas present and cannot be replaced as item sold out. Very poor service and your mail service not very reliable.

On September 10,2021 reference #125487269BP8MS order #STBYAOVUMR5FODRJ arriving from Uppsala Sweden that has arrived supposedly on September 8,2021. Homeland security check it out contained medical life sustaining medication. My husband check it out in Sweden and surely enough it is supposedly distributed by 9/8, i went to 8282 Sierra ave fontana and spoke to teller and supervisor she is more busy locating my house and mail box instead of notifying my carrier, i was ignored from 0900-1100 in which then my Blood Sugar due to anxiety drop down, my knees buckled and shaky i fell down. i came home not knowing where my medication is knock on my neighbors which were not home at that time. Richie our carrier has the habit of mixing our mails and he was told to be careful and complaint was forwarded to your office repeatedly and we were ignored multiple times. They could'nt find my mail nor did not make any effort to find it to present. This negligence among your staff need to be corrected, their failure to deliver and failure to acknowledge an urgent issue that almost cause me my physical and medical incapacitation. This final incident is a draconiac measure with disregard to human needs, that i will involve Louis Dejoy to intervene to your office for poor management,irresponsibility neglectful bahavior.

We are receiving mail that is not addressed to us so I am continually taking it over to the correct mailbox. My mail is going to different neighbors' mailboxes. Our mailboxes are in sets of 4. The are all locked personal mailboxes. My address is 14625 Labrador Ave, Fontana, Ca 92336. I think we may have a new carrier. This is happening frequently. I have mistakenly opened some of the mail that is not mine assuming it got to the right address. I do deliver it to the correct address. But, it is discomforting if I have opened it. Please help correct this problem. Nancy Elliott

This is the worse post office to get your mail delivered from. The mail hasn’t been delivered in 2 weeks. I’ve gone there twice and the mail wasn’t there. I left a message for the mail carrier and still no mail.

Through this communication, Would like to let you know the bad service that I was subjected to, this Saturday December 28,at the post office in the city of Fontana, a female African American who works there showed a very bad attention in the most impolite and inefficient way that I've never seen before in another post office. I just want to suggest a better training for these persons who deal with the public in their Fontana post office. thank you for attention to this: Ramon Hormaza

The supervisor is not helpful at all. She is not there to help anyone, but to be rude and disrespectful to others.
