I have received a faulty Honda jazz, what should I do?

Hello, I am Prashant. I just walked out of a terrible car buying experience with Honda and I need your expert advice. Basically before I could even take the car out out of the showroom I figured out that the front windscreen of my car had a fault. It's like sometimes when u look at yourself in a faulty mirror ur body looks longer disproportionate than what ur body actually is. In the windscreen case it's wavy, the road for example from my eye level feels like a moving in a wave. While when I stick my neck up it's seems ok. I bought this into my sales guys notice immediately. They said they will get the windscreen replaced but my issue is I don't want to accept a faulty product as once the windscreen is replaced it can never be as good as a factory setup. Also it will always reflect on my service record and will effect the resale of my car. I either want a new car or get my whole money refunded. Please let me know what should I do next as I am meeting showroom manager tomorrow morning and I want to know my consumer rights before I do so. Thank you. PS - More than 50% of the cars on road value is financed by Yes Bank, the rest I paid as down payment.
