Hyundai Motor India — complaint with turbocharger

Address:

797001

Hi,
The service advisor informed me that the turbocharger of my fluidic verna crdi (2013) that has clicked on 20, 000 kms has been damaged and that i need to replace the whole assembly which is costing more than ₹70, 000/- since replacement parts for the segment inside the turbocharger that's damaged is not currently available in india.
The service advisor said something about the core of the turbocharger that's damaged.
My question is why such replacement parts are not available in india? And i'm wondering how a robust component like the turbocharger got so quickly damaged since i've ran only 20, 000 kms on the car.
Kindly look in to the matter and revert back.
My location is kohima 797001, nagaland.

Regards,
Menguzelie
