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.
