Misclicked on a store offer

Hello I went to open a bronzium data card in the store and last second it switched to a deal that made me spend 3.2k crystals. Is there any chance I can reverse this deal or get a crystal refund? Its very often this happens where it'll click on something random and I almost spend all of my crystals on it. It takes ages to save them all up 

My ally code is 992-552-585

Thank you
