Skin Purchase Bug

Hello riot, recently I bought the cosmic defender Xin Zhao skin, and as a game was beginning, I purchased the Obsidian Chroma for the skin as the timer was close to 0 and the purchase glitched, the client froze for a second, and it went through for some reason as me purchasing the emerald chroma. Is there any way that this can be looked into, and I can receive the skin I actually spent money on and not the emerald one. I don't spend money often on this game, and the wrong skin is mildly upsetting. Please help, thank you.
