Honda Cars India Ltd. — Delay in delivering your car as they promised in time and they are not giving a proper response in time

I have booked brw from vision honda kottayam and they informed us that we will deliver car in 12 days because they told that the car is arriving from noida. And now its almost 22 days and they are not giving a proper response.in between the dealer told that the pearl white colour which you ordered is unavailable now. And we told that we will cancel our booking and again that dealer named prince promised that he will deliver car in time. He said he will deliver car within this month. Tommorow is the last day of this month and still they are not giving a proper response or feedback.
