@Anonymous User who told you that they wouldn't charge you any more? NowTV are very clear in all their offers that unless you cancel before the end of the offer period that your passes automatically renew at the higher price (bottom left of the attached image of last year's offer).
When you purchased the pass you would have received a confirmation email stating the same (you will have a search facility on your email client so enter 'NowTV' in the search box to find all communication from them).
If you no longer want NowTV and still haven't cancelled your active passes you should do so now or you'll continue to be charged.
You can contact NowTv via email customerservices @ nowtv.com (ensuring no spaces)
