Help! iTunes download question

[JSENNY25]

I logged in with my iTunes account and downloaded evernote.
Directly after, I was browsing the home page of the app store, I clicked on the Keynote icon and Keynote began to download at that instant.

I quickly paused the download, but the damage was done. My account was charged for a $19.99 program I already have installed on my computer.

I would really like to get my iTunes account credited.

ANY help would be greatly appreciated
(PS. I DO have the current updated version of iWork)

thanks
