We were having problems with our mail delivery person a few years ago. She was leaving the mail hanging out of the boxes, I believe, to signal her friends to break into the boxes as the mail was in there. We were having frequent break-ins, even the locked boxes were being vandalized. Anyway, I took pics of what she was doing and took it to the post office to share with post master. Next thing I knew my house had disappeared off the the delivery route and my mail was being returned to senders. I saved my evidence, as my mom and friends would send me stuff then collect it for me when it came back. I took my evidence to the p.o. and again spoke to the post master...short story, long.....the mail delivery woman is off the route. We have a new delivery person who puts mail in the box and my house magically appeared on the route again so I once again recieve my mail.
Moral, complain, you might get results, but not the results you want.
