Something like this was bound to happen if they used G2A, that place is known for being filled with scamming bastards. Im rather sure 50% of the codes there were bought with stolen CC etc, meaning when the codes don't work they were cancelled by valve for reports of using a stolen CC or chargebacks. A common issue there tbh.
G2A is problematic same.
But the Gamebet.gg staff are fantastic, certainly it is not SCAM.
With the new interface and marketing working, we will certainly have great results.
