In November I went out of town and filled out a stop mail delivery form and due to previous problems, I took a picture of it after it was stamped at the post office for proof, and they never stopped mail delivery.


I mailed very important pieces of mail on August 6, 2020, using your mailboxes located in the parking lot of your Dearborn (48124) Westborn Plaza. The pieces of mail have not reached their destinations as of September 14, 2020. I have proof of what I mailed, when I mailed it and the intended destination of receipt. In addition, there are security cameras on your property, so why hasn't my mail reached its destination in over one month?


I put mail in my mail box. But you guys don't check my water bill is going to be late


I have had a post office box for decades here. 1, Lately I have been getting mail 10 days after postmark. 2. I have been receiving other box holders mail. I'm sure the other box holders get same poor service
