Stole my money

This game is a small, but addicting game. At one point I wanted to get diamonds so I could get double coins. However, I made the 5 dollar purchase and I never got the diamonds. I tapped it again and it charged me again, without me putting in my password. Ive wasted 10 dollars on this game and I havent gotten anything back. Developers, please do something
