Q: i never received an email

You've checked the spam folder as well as the inbox on your rescue email account, and tried clicking the reset link again ?

If you still can't find it then contact Support in your country 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

When they've been reset check that you spelt your rescue email address correctly for potential future use : Manage your Apple ID primary, rescue, alternate, and notification email addresses

Or if it's available in your country you could change to 2-step verification : Frequently asked questions about two-step verification for Apple ID
