Cancel purchase?

Welcome to the Apple Community.

Apple's policy on sales of digital content is that all sales are final. If however you wish to appeal to Apple, select the content which is causing a problem and use the 'Report a problem' button in Your Purchase History on your computer.

Also note I think there is a message that appears when you already have purchased an item.

What will happen next after i clicked on "Report a Problem"? How long it will take for this to be fixed? Do you know? Who knows? Thanks.
