It's amazing the way that these Mail carriers lie and nobody does nothing to stop it.I had 3 packages coming from Amazon.The USPS delivered the 1st one on Oct 23,the second one was due on the 24th but they said my house and driveway was not accessible?That's odd it was accessible yesterday(23rd) but not one day later???????

I've contacted USPS to make a formal complaint about a very, cold, unfriendly, racist delivery carrier from our local USPS here in Louisiana. I'm not from here, and this is extremely disheartening to see the racism here. Anyway, If you speak, she does not respond at all. I don't know this lady, I've tried to be cordial, and still nothing, so I said never again will I speak to her. About a month ago, she had a field supervisor follow her to deliver my packages. She pulled her USPS work truck into our driveway to deliver packages as the field supervisor or whatever back into the people's house across the street. Today, I intentionally sat and waited for her to deliver a package, and instead of placing it on the ground or chair, she throw it as it. The South is racist, period... I would love is you could give them a thumbs down. I forgot to mention, I guess anything over 7 lbs is too heavy to leave at someone's door, just sad. It's pathic that I'm not receiving my packages all of a sudden. I'm not from this city, nor state, and this is a major eye-opener for those that are intentionally or underline racist, and in this city fueled with ugliness and hate. Update: 3/14/22 This individual works for the United States 🇺🇸 Post Office. This is an adult with hate, rudeness, etc. Sad, and I'm already tired...

I called the sulphur,la post office and spoke to manager(who refused to tell me his name) and asked about holding a package that was coming today he argued back and forth with me very rudely when I asked for information on tracking and then proceeded to hang up in my face! 08/04/21

Recently a notice of pickup for my package was placed at my old address. It was picked up from the post office by someone. Someone picked it up and no one can tell me who because they didn't get a signature nor did they ask for an ID.
