If you use a mobile banking app, or if you simply use web-based online banking, you should be able to view a list of recurring card payments.
For example, in my Barclays app, I go to my account, click on 'Manage' and then scroll down to 'Recurring card payments'. If you've got something similar, and you see something listed there which you think shouldn't be, you need to contact the relevant company. If nothing out of the ordinary is shown though, then you've got nothing to worry about. (It'll just be something to do with the way that payments get shown on your statement).
