As per our check, all the orders have been fulfilled from our end, game keys were delivered. Kindly note that you are no longer authorized for refund considering that the keys have been redeemed.
You mentioned that you did not authorize the transactions. If someone used your card data without your consent, we regret to hear about that, but cannot be held liable. We see that all your orders with us were authenticated through the 3DS method. It could also occur that you followed some partner link advertising our services and thus may not remember.
Anyway, we can only assist with refunds when there are clear indications that keys were corrupt and are still unused.
Do you have any information about who processes their payments?
