You don't have a legal leg to stand on. You should read the Terms of Use you accepted every patch.
E. Suspension/Termination.
By Riot Games. RIOT GAMES RESERVES THE RIGHT TO SUSPEND, TERMINATE, MODIFY OR DELETE YOUR ACCOUNT AT ANY TIME FOR ANY REASON OR NO REASON, WITH OR WITHOUT NOTICE TO YOU, AND WITH NO LIABILITY OF ANY KIND TO YOU. Additionally, Riot Games may stop offering and/or supporting the Game at any time. For purposes of explanation and not limitation, most Account suspensions, terminations and/or deletions are the result of violation of this Agreement, the EULA, the Privacy Policy, or the Summoner’s Code (defined below). Accounts terminated by Riot Games shall not be reinstated under any conditions whatsoever.
IV. OWNERSHIP
A. Intellectual Property. All rights and title in and to the Properties, and all content included therein (including, without limitation, user Accounts, computer code, titles, objects, artifacts, characters, character names, locations, location names, stories, story lines, dialog, catch phrases, artwork, graphics, structural or landscape designs, animations, sounds, musical compositions and recordings, Riot Points (defined below), audio-visual effects, character likenesses, and methods of operation)** are owned by Riot Games or its licensors. **
B. Game Assets, Riot Points and Virtual Items. When using the Game, you may accumulate in-Game assets associated with your Account, including, without limitation, objects, artifacts, currency, items, equipment, and/or other value or status indicators (“Game Assets”) that reside on servers operated by Riot Games as data. You acknowledge and agree that such Game Assets are accumulated as part of your Account and therefore you shall have no ownership or other property interest in any of those Game Assets. You further acknowledge and agree that Riot Games has the right, but not the obligation, to delete, alter, move, remove, or transfer any and all Game Assets, in whole or in part, at any time and for any reason, with or without notice to you, and with no liability of any kind to you. Riot Games does not provide or guarantee, and expressly disclaims any value, cash or otherwise, attributed to any data residing on servers operated by Riot Games, including without limitation the Game Assets associated with your Account.\
YOU FURTHER ACKNOWLEDGE AND AGREE THAT THE RIOT POINTS SYSTEM AND THE VIRTUAL ITEMS YOU ACQUIRE HAVE NO MONETARY VALUE AND CANNOT BE REDEEMED FOR CASH. NO REFUNDS WILL BE MADE FOR THE PURCHASE OF RIOT POINTS OR FOR VIRTUAL ITEMS OBTAINED USING RIOT POINTS. Some Virtual Items you obtain may have expiration dates while others do not, and each Virtual Item you obtain using Riot Points will be included in your Account until the earlier of that Virtual Item’s expiration date, or your Account’s expiration or termination date, or such date when Riot Games ceases to offer or support the Game.
NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, YOU ACKNOWLEDGE AND AGREE THAT YOU SHALL HAVE NO OWNERSHIP OR OTHER PROPERTY INTEREST IN YOUR ACCOUNT, AND YOU FURTHER ACKNOWLEDGE AND AGREE THAT ALL RIGHTS IN AND TO THE ACCOUNT ARE AND SHALL FOREVER BE OWNED BY AND INURE TO THE BENEFIT OF RIOT GAMES. YOU ACKNOWLEDGE AND AGREE THAT YOU HAVE NO CLAIM, RIGHT, TITLE, OWNERSHIP OR OTHER PROPRIETARY INTEREST IN THE GAME ASSETS, VIRTUAL ITEMS OR RIOT POINTS THAT YOU ACQUIRE, REGARDLESS OF THE CONSIDERATION OFFERED OR PAID IN EXCHANGE FOR RIOT POINTS OR VIRTUAL ITEMS. FURTHERMORE, RIOT GAMES SHALL NOT BE LIABLE IN ANY MANNER FOR THE DESTRUCTION, DELETION, MODIFICATION, IMPAIRMENT, “HACKING,” OR ANY OTHER DAMAGE OR LOSS OF ANY KIND CAUSED TO THE GAME ASSETS, VIRTUAL ITEMS OR RIOT POINTS, INCLUDING BUT NOT LIMITED TO THE DELETION OF GAME ASSETS, VIRTUAL ITEMS OR RIOT POINTS UPON THE TERMINATION OR EXPIRATION OF YOUR ACCOUNT.
In short, you don't own anything, Riot doesn't owe you anything, and you won't get anything. Good luck finding a lawyer dumb enough to take your case though.
