Sweetmax Charges Continue After Subscription Cancellation

I had a subscription with Sweetmax that I cancelled via your website, but despite this, I am still being charged every month. The problem started on 7 July and has continued until now. Even though I cancelled my subscription through the Sweetmax website, monthly fees of 12,78€ have been taken from my Nickel bank Mastercard, adding up to a total of 51,20€. In the attached bank statement screenshot, you can clearly see one of these unwanted Sweetmax charges. I request that all amounts charged after my cancellation be fully refunded to my Nickel Mastercard and that my Sweetmax subscription be definitively cancelled so that no further payments are taken. I kindly ask you to review this situation and resolve it as soon as possible.
