Since moving here to Winthrop Harbor, I have not been getting mail delivered. I always get the junk mail, but when I order a cd it does not arrive. I have lost at least 5 deliveries. I always get the delivery confirmation, but my mailbox is empty. Nothing on my front porch either. I am signed up for and receive postal verification. I am notified that I will receive a package, yet nothing arrives.
