Break does not work properly

Dear

I bought Datsun Redi Go from Sparsh Nissan Dwarka Showroom, on 27-12-2017. From the first day I am facing the problems continuously. In last 6 months I have went to Sparsh Nissan Service Center, Dwarka around many times. After every 2-3 days I had to go to service center for the same problem but I could not get solutions of my problem.. But nobody worried about that and they said we have not solutions of your problems and it does not matter for us what problems you are facing because we have sold the car now it's your responsibility. Do what do you want to do with your Car. Datsun Redigo is the worst car of the world. My suggestion to everyone please don't buy this car. I sent mail to customer care also many time but they did not revert also. Because I bought car for personal used then I am totally in loss because of the car. Below are the problems which I am facing in the CAR.
1. The biggest problem is Mileage(Average). Company claim it gives 25.17Km/Ltr mileage but actually it's giving mileage of 11Km/ltr in city and 14km/ltr on highway.
2. It engine make lot of noise like Eicher Tractor.
3. It's gate are very hard and make sound when we close it and at driving time also..
4. Break Pad has been end within 2 months only.
5. It's Break does not work properly if there are 4 passenger in the car. It's increase chance of Accident.

I have gone many time to Service Center of Datsun Go Nissan and sent mail to customer care also many time but nobody is solving the problem. After sale Datsun Nissan will not provide the service.

My car is totaly damaged in accident because brake is not proper work . I have got loss of Rs. 6 Lac because of this car.
