Hyundai Motor India — Complaint regarding new car

After more than a month of R&D and almost 3 and half weeks of talks with your sales representatatives at Kothari Hyundai, Tilak Road, Pune, I finally booked a Hyundai Xcent VTVT SX 1.2 'Black' HYP NYD By R.No. 49 MFG 2016 on 08th of April 2016. Earlier while in the talk with the sales person, i enquired about the colors available. I wanted a black colored car and the sales person assured me that i shall get one. Again within 2 days, when a colleague mentioned that Hyundai Xcent does not have a black color, I personally called the representative and asked her and her senior to confirm from the company about the availability of color and delivery time. Withing 15 min. they got back to me saying the color black is available, however they will have to place an order as it is not available in their own go down. Hence the delivery may take 2 weeks instead of 5 to 6 days (which is normal).
Today after 7 days, the senior representative calls me and tells me that Hyundai has stopped production of Black xcent since long time and i can choose any other color if i want. I was obviously upset. And when pointed out as to why they made the booking and started the loan procedure if the said car was not available in the first place? The person said, " I apologize. It was my staff's fault and they did not know". However refused to co- operate otherwise. I need an explaination as well as compensation for all the mental agony i went through. The people at Kothari Hyundai must pay for their incompeteance. Taking this opportunity to also point out the most rude and i dont care attitude of the staff at Kothari Hyndai, which not only us but many others I know have experienced. I hope i get some justice. attaching the receipt of my car booking.
