Hero Motocorp — Regarding insurance and service center

I have insurance for my Hero (passion pro ) bike. Bike No. DL3S ER4778. I have purchased in 2020. I had bike accident recently and went to hero service center named as Pashupati motars service center IGNOU Road, Maidan Garih New Delhi. It has been arround 12 days. A person working there said, only some parts can be changed by the confirmation of insurance company. They denied to change all the damaged part. Then, how customer can trust on brand and insurance company. At the time of buying bike, they're saying they will provide all kind of support like insurance and all. I request you kindly solve this issue. If you can't do that. I'll further take action.
