Q: Unable to access my Apple ID

If you can reset the questions yourself : If you forgot the answers to your Apple ID security questions

Then contact Support in the country where you are (and which is therefore the country on your account) to get the questions 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
