Wheres My Money?

"Pou" is a game I enjoy playing and gives me something to do, so I did not hesitate to buy 4,800 "coins" for the $1.99 deal. After I bought it, it asked me to type in my password and confirm my purchase, and it said my purchase was successful. It took my money (I checked) but I did not get the coins. I closed the app and opened it back up but I still did not get my coins. Is there something I need to do or did I just get scammed? Some help please? Thanks.
