My 10$ steam gift card arrived on Sep 8th. I copied and pasted the code onto steam on Sep 9th, but one message that says "The Steam Wallet code you have entered has already been redeemed. Steam Support is unable to issue you a new code." popped up. Apparently, someone used my code before me. Can gamekit give me a proper solution. I tried to contact gamekit in "help" but no one had responded me.
