Renault kwid

We bought 2 New Renault Kwid at Renault Centurion. We got one of them with chip marks on, both made a sound if you break and both cars smash and grab had bubbles. The one had a vibration on 70km/h. They took the cars to fix the sound the break makes, the bubbles and the vibration. We got it back with only the bubbles fixed. They took the one car to fix the chip marks and now it's a different colour. This is pathetic for brand new cars.
