my case closed because I did not response ... they attempted to contact me three times via email but I didn't received any notification for reminder or result
No one here has can exert any influence or take any action on a Microsoft account recovery. Your only options are:
Open a new support case and verify that the alternate contact email being used for the recovery process is correct and can receive email from Microsoft Support. If they have failed to contact you at your current email, try a different one. Doesn't have to be one that you own. e.g. A trusted friend or relative that can forward any replies from Support to you.
Start the Account Recovery Process directly without going thru Support.
