Drama Wave Continues Weekly Billing After Subscription Cancellation

I am writing regarding the Drama Wave subscription service. I had already cancelled my subscription about a week ago, but despite this the service is still charging me every week. Over the last fifteen days several payments have been taken from my card in Italy under the description “DRAMAWAVE-SUBSCRIPTION”, even though I am no longer using the service and had requested cancellation. I have screenshots of the recent transactions from my bank that clearly show these charges. I kindly request that my Drama Wave subscription be fully cancelled immediately so that no further weekly payments are taken, and that all amounts charged after my cancellation request be refunded to my card. I also ask for written confirmation once the subscription has been closed and the refund has been processed.
