Air Bag Light On problems of the 2016 Toyota Corolla

The airbag light on the passenger side of the car started blinking red when the car is off, when the car is on the light says the airbag is off. I took it to the Toyota dealer like I was recommended to do after checking the recall website. Auto nation Toyota at 12111 gulf freeway in houston texas for them to fix the problem. After in less than an hour the service attendant called me and told me that the car needed the windshield wipers replaced and the ac and engine filters needed to be replaced and it was going to cost 4 or 5 hundred dollars to fix. When I told her I just wanted the airbags fixed she told me the car was ready and I could come and pick it up. When I got there to pick it up the airbag light was still on as if nothing was done to fix the problem. When I told her that they did not fix the car that the airbag light was still on. I was told that there is a lot of work involved in fixing the problem to where the light would go of such as sensors, electrical, and computer resetting. And that they are only required to replace the airbag. I responded with "that was not was I was informed. I was informed that you are supposed to repair the problem and repairing the problem means that the light would go off in its original state or how would I know that the problem is fixed. " he said I was informed wrong especially if I got the information off the internet. In other words, he was telling me that it was too much work for them to repair for free. So what do I do now, am I suppose to continue to drive in an unsafe car I feel like because I was not willing to pay for the services that to be repaired then they were not going to do anything at all. That tells me that they are price gouging and doing illegal business practices and something needs to be done immediately .

Srs light is on in car indicator. And it shows there is something wrong with air bag. Bu after diagnosed by at least four mechanics it still do not show where the problem is from? ( what part?) or what's the problem? or why is srs light is on?.
