Apple funds

Hello!

I would like to request a refund, because I acidentaly transfered and clicked to add funds to apple, instead clicking the credit card, because I wanted a free trial, which for the app instructed to pay and then after 7 days refund to the card. Now, i have 300 hrk on apple funds by accudent, and I really need that money back on the card. If there is a way you could help me ressolve this issue I would be ever so grateful because I really did not intend to spend that big amount of money!!!!

Kind regards and thanks in advance!
