Fiat India — hyson fiat service cochin is not caring their customers

Address:

Ernakulam, Kerala

On 10 august 2017 i made 3rd service of my fiat punto evo car in hyson fiet service, kochi. At that time i asked for replacement of my car bumper, since it hit on a dog and crahed near right foglamp. I asked for cashless claim. The body shop technician/ manager checked car insurance and offered me cashless claim even it was taken from a non tie-up insurance brach of oriantal insurance. He said some foglamp are shortage and so they need to order it, which will take 10 days to arrive. So i agreed to come back for replacement once those shortage parts arrived; they also informed me that they will call me. But no one called me from the service center. 45 days later i called again to hyson service, but no one knows about it. So i booked a service and bring my car to the service center. I asked about the above offering and cashless claim. But they simply rejected it and asked me to pay full repair and replacement amount. I think that i was talked and got cashless repair offer from the body shop service manager (I forgot his name).

So i want clarification about the following questions.

1. Why they forget to call me after 10 day or arriving ordered parts?
2. Why they gave me false cashless offers if they can't provide if it was taken from different insurance branch? (Note: i showed insurance papers to him when they given me the offer)
