Hello,
The person who uploaded the page is a scammer and we promptly removed the page and their account. We're very sorry about the confusion. We are an open marketplace that allows anyone to sell what they've created, but we understand that this doesn't work when scammers try to take advantage of it. We're in the process of making some changes to prevent people like this from getting on our platform.
You should be refunded for the purchase. Can you contact support@itch.io with your purchase information. We don't provide support for payments on our public community.
Thanks
