Hintapp Unauthorized Premium Subscription Charge

I am a user of Hintapp’s monthly premium subscription under the email address g***[email protected] and today, at 3:55, I was charged 29 euros without my authorization. I did not knowingly subscribe to a paid plan and this is the first time such a charge has been made to my account. I request the immediate cancellation of my Hintapp monthly premium subscription and a full refund of the 29 euros that were taken without my consent. I also ask for written confirmation that my subscription has been cancelled and that no further charges will be made in the future.
