We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple.

You can try the 'report a problem' page to contact iTunes Support : http://reportaproblem.apple.com

If the 'report a problem' link doesn't work then 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

Hello,

it will be better to contact the developer first and if they cannot assist, you may seek help from iTunes Store Support as stated by King_Penguin
