I tried to buy the $9.99 minecoin pack, but did not receive it. It still took my money though.

I wanted to buy clothes for the new skin creator thingy, so I was like oooooo! I am gonna buy this $9.99 pack of minecoins. But I should sign in first, so I did. Then it showed up with me having the minecoins, so I was happy. A few minutes later it popped up saying something like "loading purchase won't take long." I sat there for five minutes confused about what was happening and it stayed on that screen, so I though it was a glitch and exited out of the app. When I got back in the app my minecoins were gone! Please help meeeeee!
