Front Driver Side Air Bag Inflator problems of the 2007 Chevrolet Equinox

I don't know if it's a takata inflator, but there was a recall for the 2007 chevy Equinox, but, for some reason the recall did not have my wife's car's VIN # regarding this recall. So, her car did not receive a recall notice! what I'm upset about is, that she has low mileage on her car, and had the same problem, just recently, and it's the same model and year, regarding the recall, that did not involve her car! I was told by gm, that because her VIN # was not "in" the recall, that there was nothing that they could do, but if I wanted to, because it's a safety problem, that I could contact you! and "then" if you told them that it was a safety problem, which it is, that you could then, get in touch with gm, and they would take care of it! so, what can be done, this shouldn't be like this!!! please help us take care of this safety problem on my wife's 2007 chevy Equinox if you would please! regarding the note below, my wife was simply driving, and the air bag light came on, and that was it. When I got in touch with gm, they did tell me that there "was" a recall on this, but because my wife's Equinox did not fall into their recall VIN #, that there was nothing that they could do! if it was a different model, year, etc. Then I could understand of course, but not when it's the same car, and model, that they recalled!!! thank you for your assistance, in any way!.
