About a month ago, my shoe order got lost in transit. Naturally, I called customer service to track it down. I sat on hold for 45 minutes, only to be told, “sorry, I can’t help you — our system says your order was delivered.”
Another time, I spent a good hour of my work day going back and forth with my medical insurance customer service and the billing office of a hospital. Neither of them wanted to take the blame for a billing error.
