bad service

I'm REALLY not happy about the service Hyundai Heidelberg have been giving me. From day one when i had to pick up the car there was some issues on that. Getting the new registration number was also an issues. One of the spotlights doesnt have a light bulb, they said they will sort that out im still waiting. Now the battery is acting up and their service manager is telling me that he cant help me cause I've had the car with me for more than 40 days. What's the point of having a warranty on the car, paying for it and not getting my money's worth? Buying a car should be exciting, a good experience. But I've had none of that from that branch since i put in my application on the car. <br>
