Harpreet Ford — Damage in car during repair at harpreet ford showroom kundali

Address:

Khasra No 31, 16, near Parnami Hospital, Kundli, Sonipat, Haryana 131028

My car had met with an accident and the bumper and bonnet were damaged majorly. The same was repaired at Harpreet Ford, kundali body shop.
When I received the car, there were internal damage to the car. There were bite marks on the buttons and knobs of the car. There were some internal parts also missing.

I have tried speaking to the RSA but he is non responsive.
