You can try contacting iTunes support via this page : http://www.apple.com/support/itunes/contact/- click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption
To try and stop it happening again your can turn off in-app purchases on your iPad via Settings > General > Restrictions, and you can also require your password to be entered for every download (the default is a 15 minute period during which it doesn't need re-entering).
