Zoomcar — Im complaining about the Zoomcar host

I’ve booked a car in the zoom app and the car’s silencer sound was from the beginning of the trip . The trip ends on 9pm march 8, I’ve returned The car at 8pm, the host was very rude towards me and asked me to repair the car and fill the fuel and denied to checkout the trip. I've filled the fuel in the car and l even accepted to submit the issue and I will pay the amount as agreed to the zoom policy but the host still denied to checkout. So I was helpless and left the place leaving the car with the host with out checkout because the host
didn't agree .I will share the details of the car and the trip, please help me to clear this issue…
