Always either delivering my mail to the wrong address or forcing me to pick it up at the post office because they’re lazy

I’am very upset & disappointed with the carrier who delivers our mail when our regular mail carrier is off. She is always talking on the phone and so loud too that she can be heard from across the street to my house. She drives away talking on the phone too. Our neighborhood is 237th & Panama CARSON CA & she delivers most of the time around 1 p.m This neighborhood is very quiet so when she comes & talking on her phone so loud, dogs bark, & sounds like some chaos is going on outside. Pls correct this matter as it is very disturbing & disappointment.

One of the mailman Alfonso needed to be counseled for his rude personality and not doing his job well. He was already informed to have the courtesy to close the mailbox door/cover after dropping off the mails due to some passers by taking mails or whenever it rains the mails get wet. It's not like he will take extra effort to lock and unlock the cover. All he needs to do is to push the cover back , same as how it was before putting the mails in the mailbox. Just a simple act to do to make a happy customer.

The worst of the worst. Having relocated multiple times I know the forwarding process. Kelly Vo is personally responsible for the suffering cash flow of my business as she has used her own personal feelings to determine what mail is forwarded and what is returned. I thought mail was federally protected? What a joke. I have multiple legitimate businesses that will confirm my mail was returned to them. She only forwards the mail that is obviously unimportant. It is a personal game and a despicable one. Try reporting her...they refer me to HER to report it to. They're like the men in blue, only the low end ones that couldn't make it elsewhere. Not all Kelly's fault? Then perhaps she should manage her vindictive staff. Either way, this place is a disgrace.

Please let me know if Contreras #4534 is your carrier. This useless disgrace to his union needs to be stopped.

Nothing short of liars, thieves and common criminals. Lying about my dog because the mail carrier got his feelings hurt, A manager too lazy to stand up to him. Multiple checks "lost" (somehow all my junk mail makes it!) coincidentally After we had words regarding his lies. A perfect example of why US Mail is going the way of the Dodo bird. I can't think of agency more deserving. I hope Contreras #4534 (they won't give his name) knows the phrase, would you like fries with that". Oh wait, that won't happen, the taxpayers can give him a nice pension for dragging his sorry a**. Useless human being, more useless management.
