grand problems od grand i10

So my problem started the day I went for grand i10 s fancy features and decided to buy this car from advaith hyundai. The nightmare started to unfold on the 1st day itself. 1st day after I received the car after may be around 20 km of driving it, a very strange burning smell started coming out of the car. It was so strong that we thought something was burning inside. Immediately next day I went back to the showroom and told them about the problem, someone came and saw and said its something wrong with the clutch. They even tried blaming the driving and I had to show how I drive even though I've been driving for last 10 years and had never encountered such a problem. So after being fully satisfied with my driving they said clutch needs to be adjusted and things will be fine. I said ok and took the car back. But the smell continued and after my repeated visits to the showroom they said leave the car there so that they can figure out  the problem as they had no clue what the problem was. So next day when I was supposed to get the car back they tell me that the clutch is completely gone and needs to be changed. Imagine my situation at that point. I bought a brand new car and it has not been driven for more than 100 km and they said the clutch is burnt. What was I supposed to do. They had no answer to how this had happened. So the clutch was changed and the car was taken on test drive by the advaith hyundai engineer me and my friend and again this time the same smell. After this point I have refused to take the car back as its a faulty car from the making and I have not paid my money for defective peice. They got one more brand newi10 grand for test ride to compare the smell and the same smell came from the other car also. So I think one whole batch of cars are defective. I would never suggest anyone to buy this car and go through the same problem that I m going through.
