The security question is not what I chose
Wrong securt question
If you have a rescue email address on your account you can use that to reset them : If you forgot the answers to your Apple ID security questions
If you don't have a rescue email address you will have to contact Support in your country to get them reset : Contact Apple for help with Apple ID account security
If your country isn't on that page then try this form to contact Support : https://www.apple.com/emea/support/itunes/contact.html
When they've been reset, and if you don't already have a rescue email address, you can then add one for potential future use : Manage your Apple ID primary, rescue, alternate, and notification email addresses
