Go to
Under the space to login on the right side of the website, there's a button that says "Forgot your ID or PW?"
Type the Image Code Verification it gives you, then skip the 1st step (that's for ID recovery but you have that) and type in your ID (hit OK) and it will give you your secret question (tho you need to know which email, so if you don't know that just try 1 by 1, tho you'll get blocked for like 10 minutes if you get wrong 3 times)
It's a pain in the *** but if you want your account back, it's the way to do it
