Agreed.
Steam froze my account to punish a PayPal dispute, the amount they would not refund was ~£2. Their refusal was contrary to UK law.
Small story about Steam. They sold me a broken game, in UK one can return broken things according to the Consumer Rights Act, specifically including digital goods. Steam said, at length, they would not refund me: the game would crash (losing some settings) after ~30 minutes, I spent more than 2h of playtime trying to fix it [it's a 50h+ game, I'd have accepted an 8p reduction in my refund!].
I complained to PayPal. PayPal decided in my favour -- ie in keeping with UK law. Steam didn't dispute PayPal's findings but instead froze my Steam account (and I assume paid PayPal the money back). PayPal made me whole, financially.
My Steam account was blocked for a month or so. Ongoing they "punish" me by making it hard for me to give them money -- which is good for me, but my kids are not keen!
WhyTF would I complain over a few £. It's the principle, clearly.
It was very interesting to me to see how a big company can ignore the law in this way. But also spend what must amount to quite a bit of customer service time just to avoid a minimal refund.
All I wanted was a refund for a game Steam sold, that was broken and wouldn't be fixed. I did cursory searching for bugs before buying, but hadn't found this particular one before my purchase.
You know what I did with the refund money, bought the next game in the same series, because it was only the bug that I didn't like, and I paid more money for it than the game they wouldn't refund ... mad, eh!
