A V G Motors - Steppiny tyre is out air and antirust coating is not proper for brand new WagonR

1. We boguht a new model wagonR on 22nd of August, after 4 days when we were cleaning the car it is found that the steppiny tyre is out of air. Then we have contacted the sales representative and he told the tyre got puctured the day before we take the vehicle and he has filled the tyre again. But yesterday when we have checked the tyre again it is found that the tyre is empty. Now the company is not giving a proper answer and they are threatening. This has happened to a brand new car and no company gives a worn out tyre.

2. Antirust coating has been done on the company (AVG motors) itself. Within 100 KM of travel the undercoating has come out. We have paid 2500/- for it and we need the money back eventhough the representative told they will repair it. There is a warranty of 3 years and it is found that the quality of the paint is very bad. In this situation we need the money back so that we can do the painting with some other good workshop
