I bought a game key for a title that's really glitchy/performs terribly. I did my due diligence - made sure everything was updated, double-checked settings, contacted the game creator's customer support, and even did a full reinstall. That particular game just works horribly when using multiple monitors. This was certainly something I couldn't have guessed would be the case prior to purchase/install (it's 2022 why would a game not work with multiple displays?!), and it definitely wasn't disclosed in the game's description. Instead of CDKeys issuing a refund or even a store credit for the broken product so I could buy a game from them that actually works, they basically just said, "tough luck." You can't always know it's a broken, glitchy game until you install it and, once you do, you're screwed - CDKeys keeps your money & walks away. I essentially got punished for making an effort/spending my own time to get a defective game working. They're just in it for a quick buck. They don't care if they're selling you poo and, when they do, there's no service whatsoever. Don't buy from them. Get it somewhere that stands behind what they sell.
