Zoom Car — booking amount not refunded

Address:

Ground Floor - Enzyme Tech park, #4 Building, Domlur Service Road, 13, HAL Old Airport Rd, Domlur I Stage, ISRO Colony, Domlur, Bengaluru, Karnataka 560071

I did a booking with zoomcar but had to cancel the booking due to unavailable car from their side. I cancelled the booking on 15 may and they have still not refunded the booking amount of 9235/-. Their twitter handle is denying to give a timeline on when i will receive my money. They can't just keep the money indefinitely. Please assist in getting my hard earned money back. It's important to us in times of covid. I have tried reaching out to them all the ways possible. This is very stressful.
