In what looked like a daring move, the CEO of Uhaul, Joe Shoen, gave out his “cellphone number” on national TV and invited customers to call him with their complaints. The problem is, when you call, he doesn’t pick up. If you leave a message, it’s not returned. You get to hear Joe’s gruffly charming voicemail message, but can’t leave one of your own. His mailbox is full.
