You know, it's a well known fact Proton still uses crony suppliers and it's a open secret these cronies don't always supply good quality parts. So I wouldn't be surprised if Proton doesn't bother with your complaints.
The only real way for Proton to improve is to remove G support, fire all the upper management and hire someone with experience in uplifting a car-business, like the Nissan CEO or VW or just some Malaysian who honestly wants to see Proton out of the drain and become an honest true to god global competitor. Not just some cheapass cheap car alternative.
