Stupid idiots! I would fight, personally, in as polite a way as possible. I'd write to the administration about my confusion over the issue, seeing as my appearance is similar to so many other people in the system. I would ask them to clarify the issue to everyone because of the rampant confusion. I would only ask for references from my director, who has no problems with it, and would have a much better idea of my performance than any administrator.

Alternatively, I would threaten the administration with legal action. This would probably make them shut up really quickly. Then I would just get my references from my director.

Alternatively, I would ignore the complaint completely and just get my references from my director. I can't believe that the administration gives a rat's ass, they're just responding to some random complaint, and if no more complaints come in, they won't care why not.

I would NOT pull my hair back. The asshole who complained would get way too much satisfaction.

Of course, my favorite live-action character/id representation was Claws-of-Gaia, and you may not want to take lessons in diplomacy from the person who played her.
