@Anonymous User (I see what you did there)
if you don’t know what you did, your best bet is to reset the router - see if there is a button on the casing you can press, or a little pinhole you can stick the end of a paper clip into - and set it up from scratch again.
Wherever possible, routers should only be fiddled with over a wired connection, or it can be the electronic equivalent of a tree surgeon sawing off the branch they are sitting on 😛
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
