I bought a used key from a scam seller and I contacted G2A support to give a refund and tell them about this seller, the seller refused to give me a refund and the support told me nothing they can do. It took almost a month talking back and forth with them. they told me to file a police report over a 12$ digital code that I bought from an online website from a seller that lives in a different continent. This website is so bad and I will never ever buy from it again. I got scammed and the ''money back guarantee'' on their website is a complete joke. Take my advice and avoid it, scam sellers are way more than honest sellers, don't take the chance.
