Soouya Charged €45.98 for a Subscription I No Longer Want

I am writing regarding a subscription charge made today by Soouya, in the amount of 45,98 €, which I do not wish to continue paying. I no longer want this subscription and I am requesting the immediate refund of the 45,98 € charged today, as well as the full and definitive cancellation of my subscription so that no further payments are taken from my card. I ask that my request for refund and cancellation be processed as soon as possible and that written confirmation be sent once the subscription has been fully cancelled.
