Storytel Charged My Card Without My Permission

Have a nice day.I started my membership to use your 1-week trial version and became a member of your application with my virtual card through the application. I did not continue using the application during the 1-week trial period because I did not like it and there was a need to cancel the subscription in your system since the virtual card was registeredI did not hear.However, your application showed my credit card as a backup payment plan through the Google Play Store and deducted the 1-year payment amount from my card. I request that this payment be refunded. You are making expenses on my behalf without my permission, using my card information that I have not saved in your application. If you do not refund me, I inform you that I will take the matter to court. Have a nice day.
