My hex-tech galio skin has gone missing

Riot, I got hex-tech galio out of a hex-tech box before his new rework and since his new rework, I no longer have the skin. Now, I realize I don't have any way to prove this other than my own word. I wouldn't be doing this if I had any doubt that I might be able to speak to someone about this. I truly do not have any intention of wanting to steal, I'd just like back what I got fair and square. Please if I could get some help on the matter it would be much appreciated.
