Q: I forgot security questions and I check no icon for rest qeustion

I check the icon for rest the qeustion and answer

If you mean that you aren't getting the reset link on the security section of your account on http://appleid.apple.com then that means that you don't have a verified rescue email address on the account (an additional/alternate email address is different).

How did you contact Support in the country where you are (and therefore the country on your account), and what happened ? They will only potentially reset the questions if they can confirm your id and that it's your account - from the bottom of : If you forgot the answers to your Apple ID security questions

If you can't reset your security questions

If you can't send a reset email, don't have a rescue email address, or can't access email at your rescue email address, call us for help. When you call, you might need to create a temporary support PIN to verify your identity. After you reset your security questions, you might want to update your rescue email address.

If your country isn't on that ‘call us for help’ page then try this form to contact Support : https://www.apple.com/emea/support/itunes/contact.html
