Hyundai Motor India — i20 asta abs failure and had a accident

Address:

Church Road, 689641

I purchased i20 asta petrol version it's almost a year manufacturing date 2016 dec. I did have complaints with break and had squeaky sound and even my hyundai dealer did their best and it would go and come back. The worst came when we were traveling with family suddenly the car in front stopped we were with due distance and applied the break however abs failed we skidded and hit the vehicle from behind and saddest part is that our abs did not locked and we went on to hit and indeed it was a bad it. I was told if it's under warranty period then company will do the needful when the vehicle was towed and taken
I went through the service report it stated the abs light was on.
Don't know the repair amount is so much does hyundai company stand with its customers for i have been using hyundai for long time never moved from it
Feeling dejected
