Innerly Charged My Card After a 0.99 Trial Without Clear Consent

I subscribed to a service on Innerly last week, where I clearly agreed to a payment of 0.99. Now I see that, in addition to the 0.99 amount, a further 49.99 has been charged to my credit card from Israel without my clear consent or understanding that such a fee would be taken. I do not know exactly which product or plan this 49.99 relates to, and I find this situation misleading. After noticing the charge, I tried to cancel the subscription myself through Innerly but despite my attempt, the 49.99 amount has already been withdrawn and I am not sure whether the subscription has really been canceled. I request that the unjust 49.99 charge be fully refunded to my credit card and that all my subscriptions and possible future payments at Innerly be completely canceled. I also ask for written confirmation that no further charges will be made to my card.
