Hyundai Motor India — I am complaining about a/c repair

Address:

Chennai, Tamil Nadu, 600063

Respected sir/madam.
I bought vehicle i20elite asta in year of 2015. My car a/c is not working now. I just handed over to hyundai plaza, ekkaduthangal, chennai-32.
The service advisor told me the a/c coil failure. Also i am using swift, innova and hyundai accent for the past 8years i didn't face any a/c issues till now. But in i20 within 30 months the coil is failure means i am just thinking about the standard of product. Also they said warranty will not applicable. While buy they said the car of the year and best of all car i am totally unhappy. I didn't expect this from the hyundai.
Thank you
Rajesh narayan.
