Bad Experience: Regretting my decision to buy Duster

I have a very bad experience with Renault Duster. This was my 1st experience with Renault car. The car is good but there are many more things that are essential when you buy a car. While selecting a car I searched all the features of duster and found them good so I purchased it. But my total buying experience was horrible. Initially after calling more than 10 times they came for the test drive. Then when buying they committed me that you will get the desired number. After 2 months when I asked about my number they said you have to pay money to get the desired number. It was more than 2 months and they have not even initiated the process. I call them sometimes they response sometimes they don’t.  It’s almost 4 months now till now I did got my RC card and the behavior of the employees is horrible. I would request to please re think the decision of buying this car.......
