Request To Block Subscription With Purisaki Patches

I am writing regarding my slimming patches subscription with Purisaki, which I believe was set up under unclear terms from the moment I placed my first order. At no point was it clearly explained to me that I would be entering into a recurring subscription or how often I would be charged. So far, I have been charged three times, each time for an amount of €58.92, paid by my credit card. I did not clearly consent to an ongoing subscription under these conditions and only realised the situation after multiple deliveries and charges. I contacted Purisaki customer service about this issue but have not received any response so far, which has caused additional frustration. I kindly request that my subscription be cancelled immediately, that no further deliveries be sent, and that all future charges to my credit card be stopped. I am not requesting a refund for the amounts already paid; my only demand is the immediate termination of the subscription and prevention of any further billing.
