From a Kappy  post
The Three Best Alternatives for Security Questions and Rescue Mail
   1. Use Apple's Express Lane.
          Go to https://expresslane.apple.com ; click 'See all products and services' at the
          bottom of the page. In the next page click 'More Products and Services, then
          'Apple ID'. In the next page select 'Other Apple ID Topics' then 'Forgotten Apple
          ID security questions' and click 'Continue'. Please be patient waiting for the return
          phone call. It will come in time depending on how heavily the servers are being hit.
     2.  Call Apple Support in your country: Customer Service: Contacting Apple for support or
          Apple ID- Contacting Apple for help with Apple ID account security. Ask to speak to
          Account Security.
     3.  Rescue email address and how to reset Apple ID security questions.
