Bad service

I bought a new ASX Mitsubishi at Rustenburg in February, since then I haven't been happy. The gear is peeling off, the cabinet is not closing properly so the light inside is always on. Yesterday when I opened the driver's door I realized that the cover on top of the door where there is an airbag is open, I do report this things but there is nothing done about it, I called the Lady named Patricia yesterday and she said sent me the picture and I will call you back, they do not honor to their promises and I regret buying this car. This is my second car and I have never had any problems that is why I decided to keep it. Mitsubishi is a disaster
