Air Bag Not Deploy problems of the 2006 Acura TSX

My wife lost control of our 2006 Acura Tsx and hit a concrete barrier head first at approximately 50mph. The airbags did not deploy. Both frame rails were bent and everything at the front of the car was pushed back towards the engine. The fenders were bent, the bumper was destroyed, the doors didn't open and close properly. My insurance declared the car a total loss b/c of the severe damage. Despite the severe accident, the airbags failed to deploy. My attempts to contact Acura and get a response from them regarding the matter has been unsuccessful. They just said "the car determined they weren't necessary" and blew me off. Their response is not appropriate to me, especially since my wife sustained neck and back injuries as a result of the crash. I want to find out what happened, and make sure other vehicles out there are safe b/c this could happen to anyone. Safety features should be functional.
