Welcome to the forum. Sounds like either the cancellation isn't fully completed or it's being deactivated by someone trying to watch movies. Pop onto your My Account > My Passes page
http://account.nowtv.com/passes
And if the movie pass is still active click cancel and follow the steps all the way to the end, there are quite a few steps so make sure you fully complete them all until it confirms it is cancelled. You should receive an email confirmation but you might want to take a screenshot of the cancelled pass as well.
As for a refund, you can try talking to live chat, explaining the situation and seeing if they can do anything for you. To get there go to the following help page

I would also recommend enabling your Payment PIN in your account, this will prevent accidental or unauthorised payments in the future. If you have a NOW TV Box it's easy for people to accidentally purchase a pass. To turn your Payment PIN on, go to your My Account > Payment PIN page
