I accidentally bought twice the Battle for the Edge expansion. I wanted to buy the Call of the Death Song but in the shop popped up a tab and I bought that one but that was a Battle for the Edge. Didn't know I can buy twice the same one. 

Can I get my gems back? Or can somehow the second purchase changed to the Call of the Death Song?
