Poor Car Servicing by Saini Hyundai

Location/place: Kolkata

Name of company/service: Saini Hyundai

I have given my 3 year old car for servicing at Saini Hyundai. There was paid internal and external cleaning/servicing among the other changes.
After the car was delivered, I can see the smoky headlight. When I asked why is it, they confirmed that it is due to high powr water jet application. But later I found that nearly a litre of water has been accumulated inside. On second time complaining they replaced it, but when they opened the headlight to fit the new one, I could see dirt accumulated in the wirings and tubes under the headlight. They were not cleaning properly. Moreover, the boot space of the car was not at all cleaned. The costly interior cleaning is nothing but an eyewash.
