We are all customers like you here, so we can’t fix this for you.
But we can ask some questions that might be pointers to how this happened, and tell you where you can go to actually discuss this with a Now employee.
Did you set a Payment PIN?
Have you sat a small child in front of an open Now account on a TV with the remote to play with?
Do you trust everybody else who might be in a position to do this?
Have you sold or given away a device with Now on it, without resetting it first?
Can you look in your Devices on your Account details, and find a device you don’t recognise, or one you do recognise but haven’t used lately?
Anyway, talk to Live Chat from here:-
and see what they say about refunding you.
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.
If you take an offer that comes with a ‘free trial’ of Boost or another Membership, Cancel them straight away. You will still get the full duration of the trial, and if you decide you do want to continue with one or another of the trial products, just revisit the Cancel, and UnCancel it.
