Hyundai Motor India — Ignorance in Customer's Safe Drive

I am a service person, and I need my vehicle in good and running condition for my day to day official jobs. I was not to write the complaint willingly. Due to not getting the Proper feedback and support from the services of Hyundai, I was really very disappointed and depressed too and it tends me to put a complaint against my issues with the vehicle Hyundai - I20 (Asta ABS) Model:2010.
Well, it is to be mentioned that lastly few months back while my car was serviced in Durgesh Hyundai, Duliajan, Dibrugarh, Assam, for the running services, one issue was left unsolved by rectifying the problem that was with my car's ABS issue and I was informed that the sensor is not available and it is not mandatory to rectify and it can be drive without resolving the issue of ABS, which was the first IGNORANCE TO SAFE DRIVE.
Accordingly, I was took my vehicle back from the service center, and used to drive without ABS functioning and it is still pending to service at Hyundai's end.
After driving for a few days, I had suddenly got another issue with my EPS, steering got jammed and cannot be driven anymore. To resolve this issue I took my vehicle again to the aforesaid service location by driving in very toughest situation totally ignoring the safe drives and was scratched by one side due to the EPS issue, but nobody diagnosis the issue and simply said that the issue is with the Motor related to the EPS and has to be replaced which will cost around INR[protected] and also currently the spare part is not available at their stocks and in nearby location within Assam circle.
This was the very biggest ignorance of Hyundai motor service center by ignoring the safe drive.
Then I thought about to service the vehicle in other Hyundai services, and I took it to Dibrugarh, Assam, which is around 50-60KM far from my location and by taking some risky drives I took the vehicle to Borah Hyundai, Dibrugarh. The response was same from them too and took my vehicle back with unresolved issue of EPS and ABS.
I was so depressed that I did not find any way to resolve the issues and It really badly affected my office jobs.
At the end, I decided to diagnosis the issue locally, so that it can be resolved anyhow. and accordingly EPS problem was repaired and resolved by locally in just INR 1000/-. which is INR[protected] less than the cost as informed by the Hyundai service centers.
and Now the EPS is running fine but, ABS issue is still un-repaired.
I am still very surprised that how a big company in automobile sector can ignore the safety and safe drives to the customers. I still question it. Does hyundai not having the spares made available or dealers are not taking the responsibilities.
It was a very unpleasant experience from Hyundai.
