Name Change?

Hello recently I was playing Crossfire and used an in-game name change. Shortly after I decided I wanted my name back. However I noticed that my name was unavailable. I know that it wasn't taken by A different player (I had some friends test some things with name changes) So I came to the conclusion that when you change your name your old name stays unavailable.
Sooooo.... Is there anyway that anyone knows that I can change my name back to my origanol name or is it forever gone?
