I am trying to cancel my account but I don’t get the cancellation option I don’t watch NOW TV
How did you sign up to NOW and pay for the membership?
Through the website, through the app, via Google play, iTunes?
Or BT TV, even?
Or directly through Amazon, TalkTalk, or perhaps a Vodafone Promo offer.
It's so difficult for me to keep up with all the NOW third party billing partners.
Also make sure you haven't created multiple NOW accounts where this happens a lot.
