The RP refund policy explicitly states that refunds are NOT possible once payment is completed.
The following is an excerpt from League of Legend’s Terms of Use regarding refunds of fees and payments. The full policy can be found here at our website: http://euw.leagueoflegends.com/en/legal/termsofuse
Section 4. Virtual Items:
You have no ownership or other property interest in any of the Virtual Items you unlock, regardless of whether you acquired access to those Virtual Items using Riot Points, Influence Points or Hextech Crafting. Virtual Items have no monetary value. You can’t redeem them for cash. You can’t obtain any refunds for purchasing Riot Points or Virtual Items, except as expressly permitted by us.
PLEASE NOTE THAT THE SUPPLY OF RIOT POINTS AND THE PERFORMANCE OF SERVICES BEGINS IMMEDIATELY AFTER YOU COMPLETE YOUR PURCHASE, AND ONCE ACCESS TO THE RIOT POINTS HAS BEEN ENABLED ON YOUR ACCOUNT, THE CONTRACT HAS BEEN FULLY PERFORMED BY US. YOU THEREFORE EXPRESSLY ACKNOWLEDGE, CONSENT AND AGREE THAT YOU LOSE YOUR RIGHT OF WITHDRAWAL WITH RESPECT TO OUR SERVICE OF PROVIDING YOU RIOT POINTS ONCE YOU COMPLETE THE PURCHASE.

The Tribunal® system allows our community of users to police the compliance of other users with the “Summoner’s Code,” which outlines the principles of ideal game play behavior, as well as with our other policies. Community members, including you, may submit descriptions of activity and actions of certain users within the Game, and collectively determine if that particular user was in compliance with our policies. If The Tribunal determines, in its sole discretion, that you have violated one of our policies, we may suspend or terminate your account on behalf of the community.

> If your account is terminated, you’ll no longer have access to it, including any of the associated data or content (e.g., champions, skins, Riot Points, etc.). You’ll not be entitled to any refunds and we’ll have no liability to you. We also reserve the right to terminate any other accounts you may have created, as well as your access to any other Riot Services (also without any refunds or liability to you).
