On 9/4/19 in the afternoon I walked into the Post Office to mail my rent check which goes to a PO Box in Rancho Cucamonga.. As of 9/11/19 the property manager has not received my check.. I had to stop payment which cost me $32.00 and they have threatened to give me a 3 Day Notice to pay or quit and a late fee on top of that.. I am a Senior and this is just ridiculous.. Is other mail list from your facility..


Envelopes with cheques enclosed are being stolen from the blue mailbox outside the post office at rancho cucamonga arrow route location.


Please get your replacement carriers to deliver mail to the proper address. You must have dyslexic retards delivering the mail as replacement carriers. This happens too often and I never get my mail when this happens. Please fire the idiot replacement carriers.


update on my situation: I got a call from the Post Office yesterday (voicemail). The message was that the package is still there and they're waiting for someone to pick it up... strange, eh? Overnight delivery service - it is exactly 2 weeks after I gave it to them and they're still sitting on the package, they did not "return to sender". By mapping, the delivery address is 2.8 miles away in Rancho Cucamonga. The voicemail said "call us" which of course won't work. How they got my # is a mystery to me but I guess it was the Help Desk in D.C. that I called with my complaint and request for help. Lady said "your package is waiting to be picked up."


I have called several times with a quick question and every time i had to give up because the computer answer sequence can not connect a person. There is menus forever and I could not ascertain the right one that would get me a human to answer a quick question.


I mailed my Mom a birthday card along with two hand made bracelets. Whoever dose our route cut the corner of the envelop and stole the bracelets and just sent the card to my Mom. I'm very disappointed that there is a theif at our post office.


This is the 3rd time that my prioritiy mail has been lost. Where do my packages go? Tracking either says it's at the post office or has been delivered. It's lost at the post office? Good job. Do new hires get training? I've also called and half the time no one answers at the Post office in Rancho Cucamonga, California. What's funny is I live across the street from the Post Office and they can't even deliver.


I'm starting to think our postal route here in Rancho Cucamonga is a training ground for mail carriers... Our regular postal worker retired a few years back and it has been a crap shoot every since then. All the neighbors get together in the middle of the street every now and then and trade mail. The postal service has become a joke. With internet bill pay and other services rendering the mail obsolete you think they would try harder..


I have a problem with their Priority Mail Pickup. Two times now you never picked up my package as directed by their pick up confirmation. Confirmation was to be picked up on 1/5/17, and they did not show up. I had to take the package to the Post Office that evening. I got a email that same day that it was picked up, which was a lie as it was not picked up. This is the second time a package was not picked up and I got an email that it was. Someone in your company is entering faults information. The Rancho Cucamonga Post Office does a bad job picking up packages. Many times I have to call and tell them that a package was not picked up, and they finally send someone to pick it up. Something needs to be done about this problem or I will use UPS to deliver my packages.
