Famradar Subscription Refund and Cancellation Problem

I am writing regarding an unwanted Famradar subscription that I am unable to cancel on my own. I recently discovered a charge of 49 euros made last Friday to my credit card for a Famradar service, but I do not know exactly which subscription or plan it refers to, and I have not found a clear way to deactivate it. Since I do not wish to continue using this service, I kindly request the immediate cancellation of the Famradar subscription linked to my credit card, a full refund of the 49 euros that were charged, and written confirmation that no further amounts will be debited from my card in the future. I also ask that you respond as soon as possible and contact me via my email address registered to this subscription.
