Hi there,
The only way to stop the billing is to contact Microsoft support and find the service and stop them, if they are done by mistake you can even get the money back . Meanwhile some common causes for unexpected charges are listed below.
-Someone you know, such as a family member, bought something with your card
-Someone made an in-app purchase from an app, game, or Office
-A subscription such as Xbox Live, Microsoft 365, OneDrive, or Skype had recurring billing enabled
-Multiple purchases were grouped into a single charge
-Your order was split into multiple shipments and billings, or shipping was delayed
