I am not sure how one can say that one has not been notified if one has been notified by looking at a list which shows the flight as cancelled.
It would seem that you have two immediate tasks:
1. Do some research to determine the best alternatives and have those in hand for when you call. It is unlikely that you will be rebooked on other carriers or outside the alliance, although redemption space itself should not be necessary.
2. Call. Do not wait as others will be calling in and they will wind up with the best reroutes while you do not.
