Accidental purchase of a skin [Refund?]

So I just purchased the skin Project: Fiora on accident. Now you may be wondering how it was an accident... I was clicking on a random skin to see how much RP i would have left if i were to buy a 1350 skin (was hoping 975 would be left). If i am not mistaken, before the shop update, it gives you a warning and a purchase review before you finally buy a skin. So i clicked on the button to buy it, assuming the same procedure still pulled through. But, and the reason for this post, it unfortunately did not. I think that it's lame to change the system, and even though it's so small, it's very frustrating because I want to use my RP on something else. I know i didn't put it in a calculator or anything, but i thought it would give me a purchase review like beforehand. I am really hoping for a simple refund of the skin before it's too late... Thanks?
