MyIQ Unauthorized Subscription Charged After IQ Test Completion

I completed an IQ test on the MyIQ website in Slovakia, after which a subscription was created for me that I did not agree to. I did not knowingly approve any recurring subscription and consider the activation of this service to be unauthorized. Despite this, an amount of 25,87 EUR has already been charged from my account for this subscription. I ask you to cancel my subscription immediately, stop all further charges, and refund the amount of 25,87 EUR that has already been taken. My contact e‑mail is: ako***@gmail.com, and I request a written confirmation that the subscription has been cancelled and that no further payments will be collected.
