Zoomcar — Refund pending and no response from zoomcars

Hello, i had booked a car through zoomcars which was supposed to be delivered to me at the Bangalore airport on 19th November 2020, one day before my booking date they called me and said that my booking has to be cancelled because the car i booked has some mechanical issue and they did not have a spare car to give me for that day etc, they cancelled my booking and told me that my refund of Rs14342 will be made within 30th November 2020, but till now no news of my Refund nor is a way of contacting them,
