Phone over WiFi, or mobile internet? The latter would be a wider issue than Now.
Have you got Storm Kathleen raging outside?
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.
