Hyundai Motor India — Manufacterer Defect or Service Defect of engine?

Address:

Kurnool, Andhra Pradesh

I was travelling to Bangalore from my home town which is called “Raichur” Via Gadwal (Telgana State) with my family. Suddenly car’s front left tyre got busted and hit the stone to engine and started leaking engine oil (Luckily, I am in slow speed i.e. 40-50kmph and we wearing belts no injury has happened) at 4:00PM on March 15, 2015 (Sunday) in between Gadwal and Kurnool. I have contacted local mechanic and just made a temporary arrangement (i.e. Fixing the oil sump with m-seal and refilling of oil) to reach nearby city. I started driving slowly and car was having smooth condition with no sound and trouble. While about to reach Kurnool (Andhra Pradesh) hardly 4km then suddenly engine stopped with huge sound at 7:30PM on March 15, 2015 (Sunday). I called Hyundai service station for any help but they told they will come from Hyderabad and drop to Lakshmi Hyundai, Hyderabad. I have not agreed it because it was too long, I have made a search and understood that in Kurnool city there is one service center called by “KUN HYUNDAI”. I called to their landline. No one lifted the call because it was Sunday which is holiday. I have asked local people and toed to reach safe location. i.e. on March 16, 2015 I have called “KUN HYUNDAI” asked to take car. They have toed the car to service station. They will look the car and let me know anything happened. After 10 days of time, they told their is two holes in engine i.e. on sump and another one is engine. So, either you need to repair the engine or replace the engine. So, we have took a decision of replacing the engine and we got it ready by after 45days and more. When I saw the engine with two holes, i.e. hole on engine sump is due to accident but inside the engine I don't how it is happened. So, I have raised the complaint agaist how the second hole in engine is happened. Now, they are telling the hole in engine is due to oil starvation. But, I have refilled the oil?
