As title stated purchased a game key and was informed by steam that the key is already in use with another account, leading me to believe the codes have been obtained through nefarious methods. Update rather than sort the issue out they would rather take umbrage with this review : "That's not how it works nor do we appreciate the slanderous review you just left considering we have been in communication and are trying to sort out the issue." No solution has been given. Now I have been accused of blackmail CS is a joke. Now they want me to provide full screenshots of my steam to prove that I'm not scamming them! I keep posting updates because the complaint keeps growing they have requested I send them a screen shot of my redemption history for arma 3 (the game the gave me a key of someone else has redeemed.) I provided a redemption history of that included the numerical/alphabetical range 1- b including the entire a section where arma 3 would reside and redemption history back to 2015! You would think this would be enough but I am informed I must provide a full screenshot including my account info to a company who has given me a code someone else has redeemed. They seem to be more bothered about the review here than the transaction they have messed up. Update: They have decided they will not be dealing with me anymore until I provide full screen shots of every game I have and my entire redemption history. Just look at the rest of their replies to negative reviews here its never their fault I know you want to save a little money but there is a reason it is cheap. Avoid this company like the plague. Update Now I have emailed steam support who confirmed the code has been used (something the customer service had assured was not possible) a year ago but apparently I now need to provide my full transcript regarding this. Honestly exasperated with this attitude.
