it did a 3:1 reverse split
you mean a 1:3 - when it is a reverse the smaller number always comes first. 12 days does sound like a long time - when there is a restructuring some brokers take a few days, but Etrade doesn't usually take that long on a reverse split. Did the company change the ticker and you may not be recognizing the new one? If not, call them up and ask them what is taking them so long. Look in your account and see if there are any cusips in place of the ticker.
