I can access it fine on my iMac.
Precisely what are you trying to do, and precisely what goes wrong, including any error messages?
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.
