Refunds

I don't like how you can refund when you're still a new player and don't get how the refunds system works. When I was still a new player, I didn't get how it worked myself and refunded my favorite champion () at the time. Next game, I realized that I didn't have her, but I had spent my IP already, so I couldn't do anything about it. I got kata again a long time later. My other two refunds were spent too because I just didn't realize how the system works. Now, I accidentally bought a champion that I didn't want to buy, and I can't refund them because I had spent my 3 refunds.

So basically what I'm saying is that Riot should make it clearer on the refund screen, or at least give the option to undo a refund if you accidentally refund someone.
