Zoomcar — Fraud with the booking cars

I have booked my car 15 days before my trip starts a new car with less km driven new and price approx : 7380 rupees.
They suddenly changed my car with old damaged car which actual price is approx 5000 rupees. But they have charged me 6400 rupees . And when I ask them for refund one week before my trip start they told me we cannot refund your booking amount as you will have to pay cancellation charge and I will get my money back in 30 working days only in Zoomcar wallet not in my bank account. This is really making Customer suffer . I have called in Zoomcar for 10-15 times in a week but they even not respond. Every one has to understand the value of time of customer.
They betrayed me.
