I'm Australian, and I think maybe the best thing about this place is the ACCC.
This time last year I was a super-hardcore valve fan, singing their praises and buying up pretty much every new game that came out for linux, including much of valve's catalog (which I had previously pirated). I was even thinking about trying to build a few steam boxes to sell on ebay.
One game I bought was Fez. It didn't work properly, making it unplayable. I emailled Fez support and recieved no response.
I emailled valve demanding the refund I am entitled to by law. I spent many, many emails back and forth explaining to them that I was entitled to my money back, since the thing being unplayable is clearly a major fault. They tried to tell me that the law doesn't apply to them and that I should write to their legal department and ignored my further emails... Rather than simply obeying the law and refunding the princely sum of $2.49.
The argument that our law doesn't apply to them is a joke - the law applies if you sell within australia. I was in Australia when I bought Fez. There are steam mirrors here. They are specifically marketing at Australians - If Australian laws don't apply to valve, where's my uncensored version of Left 4 Dead 2?
I complained to the ACCC and did a chargeback on my credit card - got my money back despite them. Interestingly, I still have Fez in my steam library, so it looks like i got it for free. I don't know whether the game-breaking bug has been fixed - I have no interest in playing it anymore.
I've not purchased anything through steam since, and Valve will never see another cent of my money - I don't support companies who think they're above the law.
The humble store and GOG have both made a killing off of me this year. I wonder if I can can get one or both to write Valve a nice thank-you note.
If you got a refund from valve without doing a chargeback, you were lucky. If you didn't get a refund, do a chargeback, then call the ACCC and tell them you love their work. And if you know somebody who works for the ACCC, hug them for me.
