The clerk at the California Avenue post office is a dumbass. All he had to do was accept my prepaid packages and that is to hard for him to do. He also said I came in with a attitude. Would not let me talk to his supervisor. Just the accept the package bro don't tell me what to do and get mouthy.


Does anyone know how or where to file a complaint about shoddy delivery service? At least three times a week we receive mail for a person the next street over. Less often but frequently we receive mail for addresses elsewhere. Sometimes the carrier doesn't take outgoing mail. Occasionally neighbors drop our mail off that has been mistakenly left at their home. I notice that the USPS website offers no option for reporting bad carrier service.


It is ridiculous how the mail carrier REPEATEDLY says there was no secure place to leave a package when we're sitting right here in the house and the doorbell never rang! This issue happens every single time there is switch of from UPS to sorry ass USPS and I'm sick of it!


tracking number for my package said it was left ( not secure location ) but post man lied . I have security cameras and did not leave no package just mail in mail box !!!!!!


my mailman doesn't deliver mail until dark!
