Demanding Refund for Unauthorized Hint App Charge

Even though I do not have a subscription with the Hint App, money was taken from my account. I do not have my card information saved with the app, and there is no active subscription shown in my Google Play account either.
This morning, I noticed that 664 TL was charged from my account, which is approximately $15 USD. I am requesting that this charge be canceled and that my money be refunded immediately.
Please help me resolve this issue.
