Zoomcar — Booking ID: JPSN7DZLH Refund not process for service not provided

I have reserved a vehicle Kwid AT (Petrol) for 30th Jul 2022 from Pune Airport (Booking ID: JPSN7DZLH). I have submitted my license and paid the full amount of INR 7656. When I arrived at airport on 30th Jul the car was not there and after calling multiple times the customer center representative picked up and told that the car will be arriving soon. After waiting another 30 mins I called up again and after waiting in the call for more than 25 mins some agent answered and kept me on hold for another 10 mins and then informed that the booking could not be processed as the Driving License is a hand written one. I told them I have been waiting with my family outside the airport for more than 2 hours but they just said they cannot do anything about it and said that the booking will be automatically cancelled and the full amount will be refunded with in 3 weeks. To my dismay I only received INR 501 as refund. After sending them multiple emails and making multiple calls finally one agent has responded saying it was a system issue and he corrected it and assured me that the full amount will be refunded in 2 weeks and I do not need to follow up again. It has been 4 weeks and I have sent 2 emails in between and no body responds. I cannot reach them on their customer service number. The call gets disconnected with the message that there are no bookings available with the number I am calling from. I used the same mobile number for booking. Such a pathetic service. Absolute waste of time and money.
