Store : GLITCH COSTS ME 1350 RP AND RITO WON'T REFUND

I recently got a $25 rp giftcard, and was quite happy to see that red card TF and Nemesis Jax were going to be on sale this month. I wanted to see whether I could get them, and still afford Forsaken Jayce, but when I pressed "Unlock", instead of taking me to the confirm purchase page, it immediately bought the skin.

Because of this glitch, I can no longer get either of those 2 skins, and RIOT won't even let me have a refund, or a partial refund. Englais
