Sweetmax-887211 Unauthorized Weekly Charges of €13.94

I live in Kosovo and I have recently realized that money has been regularly withdrawn from my account by Sweetmax-887211, even though I do not have any active subscription with this service and I do not know exactly what kind of website or service it is. By checking my account movements at NLB bank, I noticed that 13.94 EUR has been taken from my account every week for a while. I only realized this issue today, but the transactions seem to have been happening for a few months already. I have never subscribed to a service knowingly under the name Sweetmax-887211 and I have never given any clear consent for such weekly withdrawals. I request that all Sweetmax-887211 subscriptions or recurring payments linked to my card or account be immediately cancelled and that the full amount withdrawn so far, including all weekly charges of 13.94 EUR, be refunded to me. I also expect a clear written explanation of how my card details were obtained and on what basis these withdrawals were started without my explicit approval.
