Looks like we have an explanation. Of course, it should have been given the first time ANYONE kicked an order for the mistake. I see it as roughly comparable to going into a restaurant, ordering a special, only to have the waiter return a few minutes later advising that the last of that just went out... Frustrating, but it happens. But what these sellers seem to have done in many cases is just tell you it's OK to leave, you're not getting your food.
