Bought a windows pro key from them with their money back guarantee and when the key didnt work, we started a convo with the seller, no response after 7 days, so filed a claim for money back with g2a. Then after 10 days of no response, filed a buyer protection claim with paypal. Then they responded that they cannot work through 2 channels and will not refund us. What a crock! They are obviously afraid of paypal stepping in. In addition, whenever you message them they reset their 72hr support ticket clock so you keep waiting and hope you give up. AVOID AT ALL COST!!
