Hyundai Motor India — faulty engine of hyundai next gen verna fluidic sx 1.6 crdi

I own a hyundai next gen verna fluidic sx 1.6 crdi (Up 53 cp 9861). I bought it last year in october, 2017 from medallion auto sales pvt. Ltd. (Bee aar hyundai), gorakhpur (U. P.).
I am writing this mail to bring to your kind attention that on 26/12/2018, during regular checkup by my personal driver, he found out that the engine oil has reduced drastically (Almost empty) without any leakage.
Since i got first paid service of my car done on 03/11/2018 at mileage: 27662 km., from the authorized workshop i. E. Medallion auto sales pvt. Ltd. (Bee aar hyundai), gorakhpur, i immediately sent the car to the workshop for investigation. The car was attended by the service advisor sanjay kumar srivastava and he hold to leave it at the workshop so that they could find the root cause of the problem. They kept the car for three days and was informed on friday, 28/12/2018 by service advisor that they didn’t find any external leakage in the engine and they have to consult with the company (I. E. Hyundai) for further instruction. Also, i was told that since saturday and sunday are non-working day of the company, therefore they will keep the car for two more days.
On monday i. E. 31/01/2018 received a call from the service advisor again in the morning and was informed that they have talked with company and the company has instructed to open the engine to find the problem. I instructed the service advisor not to dismantle the engine and wait for my further orders.
My reservation starts here. The vehicle is only one year old and clocked only 31922 km. Mileage. The car is being used my doctor sister for daily commuting to her clinic and it is driven by our personal driver. I get the diesel oil filled from reputed, big petrol pump in gorakhpur city. We also got all the three free service plus one paid done within the stipulated time/mileage from same the authorized workshop i. E. Medallion auto sales pvt. Ltd. (Bee aar hyundai), gorakhpur also, our driver takes utmost care to keep the car in good conditions. Despite all that, the engine has become faulty. Now, opening the engine will degrade the performance of the engine and it will never be same as the company fitted. Moreover, it will decrease the value of my car.
This is not the first incident, just few days later of my first paid service, my car didn’t start. I have to get it push start my car. I have to send my car to the workshop for inspection and was told that there is no water in the battery. Can you believe it’s just few days of service the workshop guys informing that is no water in the battery? What they have been doing in 4 last service of the vehicle?
The vehicle has been lying at the workshop since 26/12/2018 and no action has been taken from hyundai regional offices despite of writing several emails to them. Therefore, you are kindly requested to take the matter with the company so that my vehicle could be replaced.
