G2A is easy as fuck, I did a lot of refund through paypal in the past years. Little tip, they will ban you at some point, this ban will discard all your future account that is connect to your ip, your paypal, your pc, your paypal cc numbers and basically everything that could be used to identify you. So my tip is to try to be as vague about your information so when they gives you the ban hammer you could start a new refund scheme with different information. I never failed a refunding g2a and I sometimes was also really generic about the problem.
