USPS complaint number 1-800-275-8677
I've had plenty of delivery issues wth these clowns. So much so, I had the multi-state district manager on the line with the local post master and his supervisor for a conference call. I told them about all the issues, how many times we've delivered each other's mail here in my neighborhood, the drunken mail lady, the mailboxes she destroyed with the mail truck mirrors, etc.
After the conversation was over, they thought I dropped off the call by hanging up...then they proceeded to talk about me and claim that I just wanted attention from my neighbors (because I gave them the 1-800 number as well). Imagine their surprise when I asked if running down their customers after speaking with them was "company policy." These people think they can provide continue to give poor service and that they can make rules up as they go if it serves their purpose. No wonder they're the butt of jokes and losing money. Any other business this poor would be out of business 100 years ago. Sorry if you read this and you work for the USPS, I'm sure there are good folks that work there too but when the USPS finally goes belly up, I'll be dancinging the street. Good luck...
