This is actually "regular" customer service. If you buy a game at Best Buy, come to find out they have a sale on that game the day after, and try to get money back for it, chances are, they'll deny you. I'm also inclined to believe companies like Steam only give you a very limited number of these sorts of refunds, just because doing this excessively can be exploited. So. As someone who, in the past, had to deal with customers trying to do what you're trying to do, sorry, but thems the breaks.
