Your Neon TV subscription automatically renews each 30 days.
If you don't want your plan to renew, you can cancel your subscription in 'My Account'. Choose 'Plan, Vouchers & Payment' and under 'Manage your subscription', click 'Cancel'.
If using a mobile device, you will need to use the hamburger icon (top left) to access the 'Plan, Vouchers & Payment' option.
Don't worry, you can reactivate it again at any time by logging back into your account and clicking resume!
