How To revert effects of an in app purchase?
let's say there is an in app purchase in my game, for 1 dollar you get 50 coins. now someone buys 50 coins for 1 dollar on play store and immediatley refunds his purchase, so technically the guy has 50 coins for free, so how do i take back 50 coins from him when he refunds the purchase?
