Hey Rohit.
See, your polo running over speedbreaker and camber setting out is an accident right. If you were driving any other polo, same would have happened. So its not a manufactruing defect in your polo. Even if shockers are under warranty till 10k, the workshop will not repair it for free because its caused by mishandling of car.
So, when you took it to workshop initially, did they ask you to put it as accident and claim under insurance?
