Unwanted app purchase by my 5 year old daughter

Apparently my daughter purchased something from itunes that I did not authorize. I do not want these items and I need for them to be deleted form my account and my funds refunded. One of the purchases was for $109.98 and one for &74.98. The app itself was free and then once in the app it tricked her into buying something else. She is not old enough to understand that concept. I need for these items to be removed as the intention of my 5 year old child was not to buy two items that were equal to close to $200. Your quick response to this matter will be greatly appreciated.

V/r,
