I lost my clan please help

Hey! So I'm fairly new to the game (around a month or so, maybe a bit more), but yesterday I got to join a clan and friended one of the players in it that was teaching me some things. Now today when I got on, I am no longer in a clan and he is not on my friends list anymore. I have been informed that apparently there was a rollback to 3 days ago, which means that I am no longer in the clan. I have a terrible memory and I can't remember the name of the clan or his player name, so I am at a loss as to what to do. I cant seem to find a clan list anywhere to look through to see if anything jogs my memory either, so I was wondering if there is anything you guys can do to help? Thanks so much!
