While what @schnapps describes will work, it’s the nuclear option, no good if you have three programmes downloaded and only want to delete one, as it will clear the lot.
I have just tried @Sandey‘s much more pinpoint method, the one that Now intend that you should use, and it works a treat.
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.
