Welcome to the forum.
If you go to your My Account > My Passes page http://account.nowtv.com/passes you should see that the passes you have are showing as cancelled, along with the date you still have to watch until (they will carry on working until the expiry date of the pass). You should also have received an email confirmation.
However if you want to double check for your own reassurance, you can email or ask live chat by going to the following help page
http://help.nowtv.com/article/None-of-the-above
and click the green Contact Us button near the bottom left of it (not the How to Contact Us link right at the bottom as that takes you somewhere else) then choose the Email or Live Chat option on the following page.
