Zoom Car — wrongfully levied vehicle damaged fees

We had booked Swift on 13 Jan 2018 from 7:30 am to 13 Jan 2018 12:30 am with id: JPS62LL74.We got a call before 2 hrs of starting our trip to inform us that they have upgraded the Car from Swift to Creta(KA01AH2744) and we agreed that.We finished the trip and returned the vehicle in perfect condition as it was, there was no damage in the vehicle made by us. After that, when we checked our zoomcar account, found that they have charged 10000 rupees for vehicle damage fee and complained about it and also shared a video of the car that was taken by us before starting the trip. But they are saying that the car has a major damage. Even after having no damage from our end, they have charged the amount(Rs. 10000).
Request a refund for the amount as it is charged wrongly against us.
