Zoomcar — No response and not refunding the money

I booked a zoom car for Wednesday 11 pm. One hour before the trip, the host called and cancelled. He informed that he was unable to cancel it from his end and hence told us to cancel. We tried calling zoom car multiple times but got no response. We have been trying to reach zoom car for three days now with no response. We have not received any refund or response from them. When I tried to ask updates on my compliant, they informed that I had no outstanding complaints. I have paid Rs.8, 500/- and they have vanished with my money.
