Zoomcar — Fraud, company is claiming possession of rental car is with me, I never received car.

I booked rental car from zoomcar app. When I reached location where car was parked, car was missing I waited almost an hour around 2 PM. When I was not able to find car I raised complaint in zoomcar app informing that I was not able to find car and trip was not started I also tried calling owner of car multiple times calls went unanswered. 7PM I received message from Zoomcar to leave car at the location then I came to know that someone has started trip of which I have no knowledge. Currently app is imposing fine on me because as per them I have not returned the car whereas I don't have any car with me at all and I never had possession of car. I tried contacting zoomcar multiple times through call, chatbot (in APP) and email, nither zoomcar has responded nor Owner of car. I have not received any refund instead company is imposing fine on me.
