The lady who delivered today, 08/7/19 runs the route that runs through Walnut Ave in Winton ca 95388, never hops off the vehicle to leave packages, if no one comes out to receive the package she marks it as no one was present and does not leave a note or anything that says she passed by the only way we know is that the mail is left behind but packages are not present. It’s been on going but today got me especially frustrated because I pulled up right behind her as she delivered our mail and honked at her, she seen me and as I walked towards her she took off and I tried catching her at my neighbors house and she seen me coming towards her and threw his mail in the box and sped off down to the next house. I don’t want any of the other employees getting in trouble because they are always professional it is just that one lady we always have issues with. If it’s going to continue to be like this i will just begin opting out for the competition because this never happens with fedex or ups!


If it helps, I know a lady who delivers mail for USPS here in winton. She's my neighbor. Come pay a visit.
