Poorest service

<p>I bought a brand new Renault Duster on the 15/06/2017. In two weeks the car started showing an engine warning light. Since then the car has been in and out of the dealership. They refuse to replace the vehicle. They said it will be ready by 21/07/2017, but I've had no communication from them. Ive requested a diagnostic report several times, but all I get is empty promises. I'm sick and tired of being sick and tired </p>
