A common mistake that new users make is assuming that Now staff monitor postings here, and address users’s problems.
They don’t; you are talking to fellow-users like yourself, and though we may be knowledgeable, and try to be helpful, we can’t address billing issues like yours, alas.
(The blurb at the top of the Community explains this, but there is nothing to make you read it 😢)
The best we can do is go into ‘signpost mode’, and at least point you to where Now staff do hang out, and should be able to help you. So…
The following link leads you to direct contact with Now, for when the Community can’t help, and the Help can’t help:-
From here, you can contact Now via Live Chat.
Avoid ‘Get Help Quickly’ when you come to this screen. This leads to the Nowbot, an AI bot that might well assist you in navigating the Help; but as you have reached this state of affairs, you have already gone well beyond that, and all the Nowbot can bring you is frustration.
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.
