So my "friend" disenchanted Hextech Annie as a prank after I unlocked it.

It's exactly what it looks like in the title. Earlier today, I opened my 3rd chest ever and got the Hextech Annie skin, I was at my friends house using a LAN and he freaked out about it though I had no idea what the big deal was since I only just started playing the past few days after a few months break, I went to go piss and he asked if he could disenchant it since I told him I never played Annie that often. Later today, when I joined a group of other friends I told them about the skin I unlocked and when I told them I had disenchanted it they freaked out. My friend who disenchanted it was laughing hysterically in the skype chat while the rest of them were outraged. Needless to say I wasn't in on the joke until after the fact.

After researching it and bemoaning about it in other games I was really pissed off and wanted to know if I could have any compensation, either getting the skin back or anything, thanks :)
