No parts, arrogant service

I originally took my Renault Duster in due to loss of power, Renault turned me away verry arrogantly saying there is nothing wrong with the car, a week later I had to tow the vehicle there with a failed injector (seemingly a known problem with the car) , Renault has no spares and despite accepting the orriginal timeline of three weeks to wait for parts this has now become a unknown duration, my car is riding out it's last few months under warranty at thr Renault workshop and I just have to make another plan to get to work and back.

Never in my life will I own a renault again.
