"If you purchase digital content - such as music or a video online - you cannot withdraw once downloading or streaming has started, if you previously agreed that you would lose your right of withdrawal by starting the performance."
That's how Nintendo of EU gets away with not refunding. You started downloading it so no returns.
If they don't want there is small claims court which is cheap and simple. I have used it in cases where some manufacturers would void warranty due to "water damage" after the product stopped working. In the end they paid: cost of purchase, cost to file, cost of my legal consultation, cost of expertise showing that there was no sign of water damage. Country - Poland.
Sony too.

Do you think that Steam is even failing that, with the extra requirement of maximum 2 hours of online play ?
(Compare with GoG, where there are no online play requirements, since you can just play and even install all games offline.)
