Welcome to the forum.
Try popping onto live chat, explaining the situation and seeing if they can do anything for you. To get there go to the following help page
https://help.nowtv.com/contact-us/how-do-i-cancel-now-tv
Afterwards go to your My Account > My Passes page and make sure you cancel any active passes on there that you don't want.
I would also recommend enabling your Payment PIN in your account, this will prevent accidental or unauthorised payments in the future. To turn your Payment PIN on, go to your My Account > Payment PIN page
