Fed up with i20 brakes and suspension issues...noise problem

I bought i20 sportz 2017 December month (petrol) model I would mostly drive in city traffic...so I often use the brakes One fine day I applied brakes it doesn't work after applying second time it works...that was the most nervous moment as I was traveling alone...The 2nd one is on driving on the rough road it making very bad grinding noise ..feel as if the iron rod is rubbed towards a concrete block ..o faced this problem many time.. asking to the service centre they doesn't respond very well ..I am living in chennai.... I bought this car as everyone like to purchase this car ..it hit the road in the well form...but after this issue I don't know where the other people also facing this same problem or I am the one who facing this problem... Please notify me guys .. they haven't seeing this problem in the 1st service.. I already told them about this problem... No action was taken😡😡 I am going to mail this mater to the higher authority through mail ..we r the customer they have to satisfy our request...there is no other way except doing this ..thank you👿
