c) doesn't work, because the companies don't want to carry the costs associated with it. If you've ever been to a customer service center (or whatever they call them) at UPS or FedEx, you'll know what I'm talking about. Long lines for the single desk manned by someone who clearly does not want to be doing that job and shows it by every interaction with customers. Also the important point is that the people who the packages are delivered to aren't the customers. The companies that ship the packages are. So unsurprisingly the carriers don't really give all that much of a shit about how you feel about their service. Unless a really egregious customer service failure goes viral for some reason.
