the reason you are being asked to pay is because you submitted your question to JustAnswer, a third-party pay support site rather than Apple. We are not Apple but we do help Apple owners every day.
If you wish to continue and agree to the service I would be glad to assist, otherwise you can request a refund, etc...
I am not an employee of JustAnswer and do not have access to your account details to handle requests of this nature.
You can access http://ww2.justanswer.com/help for account help or contact customer service directly via***@******.*** with any financial concerns.
If you change your mind I am here to assist.
