Hyundai Motor India — Right door key less entry

Address:

Kolkata, West Bengal, 700026

I am a proud owner of I 20 elite Sports O I had sent my car for service in the month of Nov 15 for a Warranty Claim of my key less entry on my right driving door which was not working, I was informed that the product is unavailable and once available they will inform me now I sent my car for service last week and asked for the claim post which I am getting a response from the service advisor that the same is not possible as the warranty of the car expired on last Nov 16 I insisted that I claimed the same under warranty in Nov 15, Due to unavailability of the product was not replaced.
Request you people to take necessary step as I claimed under warranty it's your service station who was unavailable to provide the product and as a customer I can claim the any next time I visit.
My car is there at service at Saini Hyundai Service Station WB, Repair Order number for your car is R[protected]
