Stole my card details from my online transaction history and stole my money

I am very disappointed in you I have never used my card to buy any content from play store but you managed to trace my card since I use it to buy online and bought an app that i downloaded for free and used the trial.after expirting you decided to take my money without me entering my card details and approving that transaction .that is ***** because for every transaction weather online or at shop I should approve it via the app or password for it to go through but you bypassed all that and took my money R895. I want my money please
