Invalid key sent and horrible customer service
Gaming Dragons sent me a key that just doesn´t work. I tried to redeem it multiple times on Steam and nothing. I sent them an email and they replied 20 minutes later asking for some screenshots where they can see my Steam Library and my profile name (?). After that, hours keep passing and I have received no answer. I hope that they send me a new code or a refund ASAP. At least they could say something like "We will fix your problem asap" or "we are working to fix the issue and will contact you back soon" or something!!
