You brought up an important point, but there's a detail that's not as straightforward as it seems. Yeah, default options are legally questionable, but it varies a lot depending on where you buy (each country has different regulations) and what exactly the contract you accepted when purchasing says. Before assuming "they legally can't charge you," check the platform's terms and conditions carefully, because some sites do allow it if it's visible at checkout, even if it's shady. Your best bet is to send an email with screenshots showing the screen and asking for a refund, but be ready for them to say they saw agreement in the terms; if they refuse and you're sure it wasn't your click, escalate it to consumer protection.
