My friend got me a Minecraft gift card so that I could redeem it for Christmas. I redeemed it and it was successful. The website then told me to download Minecraft so I did. I opened it and it said play demo. I was really disappointed and tried to log out and log back in and nothing happened. I also got the transaction confirmation sent to my email which I will attach an image to this report. I tried using the code again in the redeem section and it said that it is either invalid or it has already been redeemed.
