It was tough because at the time I couldn't go to help him in person. And even when I finally could, it took months of waiting and even contacting an old college roommate at FB to help get it unlocked. It was probably 8 or 10 months later that he finally received an email and could go reset his password.
I really wish these multi-billion dollar companies would at least staff a helpdesk to field these basic issues. When these "free" services lock you out, you're basically left with yelling at what feels like a wall trying to get help.
