Datsun Redigo is Dumb Car, Don't purchase, Service is 3rd Grade

I've bought Datsun Redigo before a month from Ahmedabad, Gujarat... I have given my car for first free service at their service centre.. I am surprised having this experience.. I've also experienced service quality of Maruti & Tata..they are the best as compared to Nissan and Datsun..My petrol has been stolen from my car which was more than 12 ltr.
Gear box & clutch are so hard, they are not ready to accept this problem. Although they are arguing these are the common in all datsun cars. They have not taken this as service problem.
My Common Problems also not solved even after 6 hours of services.
In this first service, I've wasted my 6 hours-almost whole day & at the end of the day Igot very disappointed.
So guys this is my humble request not to purchase this dumb car.
I think from service point of view Tata & Maruti are the best... Nissan provides very low level of customer support.
