Trick to get Equifax credit report after being denied due to “Security” reason

I recently tried to pull my credit report from for Equifax. I had given all the correct answers but still I was not shown a credit report due to “Security” reason. They mentioned that I should mail the request along with the proof that I am myself. What I noticed is that the questions are very wierd compared to what Transunion and Experian would ask. A quick google search regarding “cannot get equifax credit report” reveals the same problem other people are facing. I knew I answered all my questions correctly and still being denied a federally mandated report so I filled out a quick “Contact Us” form on complaining about it and to my surprise I got my credit report in mail within 7 days.
