I was charged by iTunes twice about amount $32.09 while I didn't purchase anything from viewing my billing history.
I've checked online and asked other people and they also had met the same problem, can you help me with this?
You haven't made any in-app purchases or have any auto-renewing subscriptions ? If not then you can contact iTunes support via this page (these are user-to-user forums) : 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
