Long story short. I've bought multiple keys from them over years, if you only buy from high sellers with good ratings you'll be fine (I guess now). But the first time I didn't, I got scammed. Basically the seller bought a key from Bethesda, sold it to me via G2A and then asked for a refund from Bethesda, 2 days later my key is invalid. I've followed procedures, reported the issue and contacted seller through G2A which tried to extort me to change my feeback from negative to positive otherwise he won't pay me which I refused, then he told me upfront that he won't pay me jack **** and wished me "good luck" getting the money back from G2A which sent me a template response, they're still ignoring me a week after it happened, support is miserable, they don't care about you once they got their money. I opened refund case through paypal and they didn't answer once in 9 days since opened. The type of behavior the seller showed shouldn't be accepted but it seems they're more than tollerating it. I'm done with them after this interaction. Moral of the story: Buy it from the game publishers directly, Steam or other marketplaces you trust. Also this was only my experience, but take note. Still haven't got my refund.
