Welcome to the forum.
Did you apply your voucher to your account, if you don't then any passes already on your account will automatically renew unless you cancel them.
If you have a voucher code you don't need to wait until a pass expires before you apply it, you can apply it anytime when you have less than a month left, and the voucher will then kick in automatically when the current pass expires.
I would also check on your payment history page http://watch.nowtv.com/account/orderHistory to make sure the money has been taken out of your current account, as sometimes people have old accounts they've forgotten about and not cancelled.
