Do I have a strong case, and if so what is the procedure of taking this into concern since my air bags failed to deploy in a heavy impact to the car?

I was in a car accident a couple of weeks ago. I was hit by a car driving at 50/60mph and the car was literally torn apart. It spun out of control and bounced off a lamp post. My car now is a total loss and the damage done to the car was £7.860. The only issue was that air bags failed to deploy with the severe impact done to the car. I had my seat belt on but I was literally thrown around in my seat. I had bruised my whole right had side of my arm and shoulder as it hit against the door and the side of the car. This up until now is still very sore. I also hit my head against the steering wheel which cause of the force of the collision. I then hit my head on the head restraint. Since the accident, I have been and out of hospital and the doctors, with severe pains. I was told by the hospital that I had concussion and whiplash. I have been having severe headaches which are worse than migraines. It literally feels like I’ve been hit on the head with a hammer. This pain is consistent, mentally and emotionally. I feel depressed and drained because of this accident. I am very shocked that the airbags didn’t go off. I drove a Volkswagen golf TDI 1.6. The car was on finance with VWFs. When I took the car out on finance, what interested me about this company was because of the quality of the car and the safety features. I have been on finance with VW for many years now. I want to take this further and get some sort of compensation for my loss and the pain I have to suffer due to VW's safety features failing. I am now very nervous to drive another VW car cause of this. I am based in the UK.
