Disgusting Service at Hyundai the Glen

I bought an I20 just over a year ago. When I bought the car a few weeks in I advised Hyundai that my brakes were making a tapping sound. I was told because the car is still new the brakes will eventually come right. This did not happen. In March 2024 I took my car in for the first service 15000Km. I clearly stated to Hyundai there is something wrong with my brakes its making a tapping sound. On their records it does state that I asked for it to be checked. They acknowledged that it has been checked. On the 7th July I met up in an accident where my brakes failed. I had my kids in the car on my way to drop them at school. My brakes did the exact thing that I reported to Hyundai to date. I had to use the handbrake to stop the car. My wheel hit the pavement and I had turned 180 degrees to avoid the car infront of me and almost landed in a shop. I went to the nearest garage to get my wheel changed and drove straight to Hyundai the Glen. Spoke to the service manager which said I should leave the car there for them to check the brakes. I get a call from Sydney the dealer principle to advise me that they took my car to check the brakes at Dekra which confirmed that the brakes is fine. I then asked him to give it to me in writing that the same thing will not happen again, which he responded that he cannot do that. NOW, how does Hyundai expect me to risk my life and my families when you cannot guarantee safety for your brand. Its a new car, You did not give it to me for free , I paid you for it which was not cheap for a piece of junk. Now you expecting me to claim from my insurance for a fault that you were made aware of. TAKE SOME DAMN ACCOUNTABILITY. You were very eager to sell me this car and sell me all the benefits. But it does not live up to you standards that you portray. No one can speak to a senior or your CEO seems to be unreachable , is this a status thing. Your client experience is in the minus in my view, you have not ethics and values. This was a know issue to Hyundai yet you expecting me to pay for your negligence.
