I canceled my subscription, but Apple sent me receipt

I wanted to get app “ FunShot+”. I scroll down the information in order to be sure that it is free. When I did not find any information that I must pay, I made subscription. Immediately, I received email from Apple about Subscription Confirmation.... but also with price. I canceled my subscription, but Apple sent me receipt and withdraw money from my card. In my opinion, it is fraud because I didn’t allow withdrawing. And I even did not know that Apple has my payment method.
