Classified im in a similar situation as you im 22 and almost everytime I goto the dealer to report a problem no matter how big or small it is they pretty much disregard it as abnormal wear and tear.
So to solve the problem I just took the car to another local dealer and explained that the car had been back to the dealer I bought the car from and I was dissatisfied with how I was treated, and they were more than happy to help.
Last 2 times my car has been to them, once for service and 2nd to fix an issue they have thrown me the keys to a loan car, free of charge and no petrol cost. So like others have said, if you not happy just take it somewhere else.
