Not what I expected!

I wanted to be able to hear the pronunciation since I had already bought the voice in another app from this company. It gave me the choice to buy this app so I clicked buy and nothing. So I went to the app store to verify I had bought this app, but it seemed it did not work. So I clicked "buy" again. The app turned out not to be what I expected. Then I go to my "balance" and they charged me twice on the same app!!!
