Molded Renault kiger

Just bought a brand new Renault kiger life for my wife for valentine. Not even 2 weeks in i found out the exhaust system is rusted. We contacted Renault Table view they sald they can fix it when it gives problems. Then we see the silver on the front grill has mold on it we took it back they tried to clean it ,but couldn't. Now the brand new car must go back so they can replace the front grill and exhaust. But take in consideration this is a brand new car . We dont want the car anymore. The best valentines day gutf turn into the worst ever
