Having recently sold a book on Half.com I encountered a problem with their system. Something has gone awry and they are sending the notice once an hour. When one ventures to their help desk, however, it's anything but helpful. Eventually if the customer is persistent they find out that the customer goes through the help wizard to get to contact support. Mind you the help wizard has no canned questions that are remotely related to the question at hand. So for a problem with the order system one is reduced to submitting the question about I received an order, but cannot find the shipping address for the buyer.
