Honda — About destroying the clutch plate of my car

Address:

Shimla, H. P

I am using honda city ivtech since many years and drive my car very carefully and i do proper care for my car. I get serviced my car from Himalyan honda dealership in Shimla on 28.03.2021.
When I reached the dealership, clutch of my car was working properly and i handed over the vehicle to their staff. The way to enter the dealership is very congested and very steep. They parked my vehicle on that steep road and several times they moved the car reversing and forwarding to give pass to other cars exiting from there and many of their workers driven the car reversing on that steep way and put a lot of pressure on the clutch and made it weak. When i got back my car after service, i experienced some changes in cars performance and its pick up was also very weak. I'm sure that the clutch has become weak due to their mishandling. My car is only 34400km.run and single hand driven.
I request to take action about this matter.
