I was sitting in my living room about 6:30 pm on Monday, April 3rd at 128 Donna Ave. Darien, Wi. 53114, when the mail van arrived, delivered my mail and as they drive away, hit my mailbox, knocking out to the ground. They drove away and made no attempt to fix it or tell anyone. I was able too get it back in place, but they broke the plastic mounts, so I doubt it will last long. This is probably at least $100 to replace. Who do I talk to?
