Ourhobbyfun Charged My Card €2 Without Consent

I honestly do not understand how I ended up becoming a member of the Ourhobbyfun website while I was shopping on Decathlon. Please cancel my membership immediately; otherwise, I will file a complaint with higher authorities. A membership was created in my name without my consent, and €2 was charged to my card account without my permission.

I am requesting a refund of the €2 that was charged, and I also demand that the membership created without my authorization be canceled immediately.
