Q: security quastions

If you aren't getting the reset link then you don't have a rescue email address (an alternate email address is different) on your account, and you won't be able to add one until you can answer your questions - you will have to contact Support in your country to get the questions reset.

Contacting Apple about account security : http://support.apple.com/en-us/HT5699

If your country isn't on that page then try this form and explain and see what they reply with : https://ssl.apple.com/emea/support/itunes/contact.html

When they've been reset you can then add a rescue email address for potential future use : http://support.apple.com/en-us/HT201356

Or if it's available in your country you could change to 2-step verification : http://support.apple.com/en-gb/HT5570
