depends: Based on what I understood, he gave you everything but the SQ and told you that he doesn't have and/or know the e-mail. So you gave him the wrong number or haven't completed the number. Then you checked the account, turns out that he has changed pass (am I right so far?) then you didn't give him the code and you didn't get the account. So if all that was said previously is true, then he IS the scammer and you just did the right thing.
