Zoomcar — Money not refunded

I hired a car from Zoomcar on the 11th of October 2020, it’s been 20 days and still, till now i haven’t received me security refund amount back. I was told the refund will be done in 24 hours. I dont know why it’s taking too long for the refund. Also the car condition was pathetic about which I had complained. I have email them many times but they are not providing me any resonable response.
