Account Recovey Question

Hey,
Let's say you're trying to recover an account, and it's your account. You know all the info ID, password, security. And, if someone was able to steal your account (not the e-mail, but your Crossfire account), and change your password, security, in-game name, and e-mail, could you, the origianl owner still retrieve your account some how?

yes its hard but ive done it b4 i acctualy had to call them and give them all my info i ever used on the account like the last 10 times i used my Credit card or IP adress for the last 2 years stuff like that and i ended up geting it back after a month
