Hyundai Motor India — Poor servicing and stolen vehicle component

Address:

Kamal Automart India PVT LTD, IPIA, Jhalawar Road, Kota

I had serviced my I20 Active from Kamal Automart PVT LTD, Kota (Authorized service center of Hyundai)
The servicing done was very poor that on the very next day I had to replace all the spark plugs that too on chargeable basis.
Also, Navigation SD card found missing after the service. Service center is denying responsibility and asking to purchase new one.

The case of mental harassment of customer.
