@MojangSupport we just bought and downloaded Minecraft but every time I tried to log into my account it tries to make me pay again. I know we payed for it because my mom bank emailed her that she purchased it.
If you've received an email with a Transaction ID from Mojang, the purchase was successful and you should be able to create your profile here https://accounts.mojang.com . If not, we recommend contacting your bank to resolve any pending charges. ^SA
