The Worst Car of the World

I bought Datsun Redi Go from Royal Automotors Showroom, Sanganer Road, Jaipur on 3-01-2017. From the first day I am facing the problems continuously. In last 3 months I have went to Royal Nissan Service Center, Sitapura Jaipur around 20-22 times. After every 6-7 days I had to go to service center for the same problem but I could not get solutions of my problem. I had complained to the GM of the service center Mr. Abhinav also. 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 Taxi Purpose 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. It's Diggi gate block automaticallly after every 7 days.
5. Car get imbalance if you run it more than 100km/hour speed.
6. It's staring get hard after 2 months.
7. Break Pad has been end within 2 months only.
8. 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. I have got loss of Rs. 6 Lac because of this car.
