Unauthorised Transaction deducted

I have noticed that transactions are being withdrawn from my bank account every three days, and I am unclear about their nature. I have reported these unauthorized transactions to my bank on several occasions, categorizing them as *****ulent activity, and we have replaced my card three times within the last six months. I find it puzzling that Microsoft is able to initiate payments from my account without my consent. Generally, subscriptions are charged on a monthly or annual basis, but these deductions happen every three days and involve substantial sums. Additionally, despite canceling my card, these transactions persist.
