Ruego me ayuden a cancelar mi suscripción gracias muy amables, ya que no es lo que necesitaba, y me han descontado del banco ya el importe de 8.12€.gracias por la atención prestada.

and make sure you're aware of the cancellation terms by selecting your plan type (at the top of the page here), https://helpx.adobe.com/manage-account/using/creative-cloud-subscription-terms.html 

if you want to cancel but are unable to follow the steps described in the "how to cancel page", you probably have a payment error that you need to repair before cancellation is allowed, https://helpx.adobe.com/manage-account/kb/fix-failed-missed-payment.html
