Thanks for taking to comment on your recent experience on G2A.
I am sorry for any misunderstanding occurred. It looks like you bought a key that cannot be activated in the USA. Please mind that this information is clearly visible on the product page, so you can make an educated decision on what you are buying. In such circumstances, the seller might not agree to refund or replace the code with the Global once, since you received a product as was advertised. Additionally, you've already displayed the code, so the seller cannot be sure that it's still valid and unused.
Additionally, if you have any difficulties with reselling procedure, please do not hesitate to get in touch with our Seller's Support at firstname.lastname@example.org, they will be happy to assist!
