I naively disputed Steam not honouring a refund (it was for about 0.5% of what I've spent with them up to that point), a couple of £pound at most. I'd paid by PayPal and as Steam refused to abide by UK law (Consumer Rights Act says broken stuff has to be fixed or refunded), I raised the issue with PayPal. I expected Steam would refund me, instead they did not dispute that they'd unlawfully failed to refund me, so PayPal - Steam's provider - cancelled the charge.

In response, Steam 'limited' my Steam account - effectively closing it temporarily. Now it's limited so they won't use PayPal to sell me anything now, so I haven't bought anything from them since [I have cashed in CS skins, and used that cash to 'buy' games].

It was an interesting lesson in 'might is right'. PayPal were able to refund the transaction because Steam want them and had no argument against the refund. Steam were able to cut me off because this appears to be a loophole in UK consumer law - sellers who break the law can just dismiss buyers who ask for refunds. Lesson learnt.

From Steam's point of view, they pissed off a customer and probably burnt 30mins-1hour of support time in answering my requests, way more than the cost of the refund. But selling games, which I later found Steam knew was broken, and then not refunding because I had the tenacity to try and fix it - meaning that the game sat open for longer than their auto-refund time - is not on imo. Petty of me for sure. Crap of Steam too.

I'm surprised UK law doesn't prohibit retaliation against the customer for insisting on his legal rights.

Not petty of you IMO. It's what everyone ought to do but it's inconvenient so most people don't.

I grew up when we owned game systems and the games, and they couldn't phone home to see if I still had permission to play. I was recently considering installing Steam but this kind of thing gave me pause. I couldn't invest any money in something that could have the rug pulled out from at any time.
