I bought Minecraft but my account says I haven't?

My mother allowed me to use her credit card and pay for the pc version but when she checked her bank account there were many transactions, i think there were seven, some were $1 and some change, one was $7 and some change and then the last one was $14 and some change. Not sure if this is normal but my mother is upset for we're unsure if it had charged her several times. I read that they send a transaction ID email but i have yet to receive the email. Also the account I made with Mojang says I have yet to purchase the game. Can someone reassure my mother and I that this is normal for purchasing online.
