Its not working, i have g2a shield (fresh account).
All rep tell me to contact seller, after 3 days dispute with seller, no response.
And g2a rep tell me this in the dispute : The Buyer is requested to contact Blizzard support in order to determine when exactly the key has been redeemed (date + time) and provide us with a screenshot presenting the conversation. The key has to be mentioned in the exchange.
Can't refund g2a anymore just with chargeback paypal
