More refunds/ive spent alot of money on here and think we should get more refunds

i Feel like Riot games should give us like 3 extra refunds ive spent well over 300$ on this game and i think i should get another 3 refunds. ive bot a lot of stuff i dont want and now i cant refund it because i wasted them when i thought you got more over time. and i wish there was a test button so you could go in try the skin u want or try the character you want. ive spent alot of money on champs that i dont want and want to refund because i dont play them or ill never use them. this is why i think they should make us earn more refunds overtime or just give us a little more as a gift.
