I don't know if there's something you could do about this, but a friend of mine borrowed me their credit card cause I don't have one. When I tried to pay for the game, the page said that the security code wasn't correct so we tried with another card and the same thing happened. Then my friend realizes that both cards have been charged for the game but I still don't have access for it and the games is charged twice.
I've sent itch an email and I hope this is resolved, I'm really sad I can't play the game and preoccupied because of my friends credit cards.
I just wanted to let you know and hope that maybe you know or could do something.
Edit: Itch didn't communicate with me but my friend's money is back now i don't know if itch had something to do with it. I'm going to try to get the game again.
Edit 2; I tried again with another credit card and the same thing happened again, the game is charged but now the itch page says that the card has been declined. I'm really frustraded about this.
