Zoomcar — Security deposit not being refunded

I’ve subscribed to zoomcar for a month which requires a refundable security deposit of ₹5000 at the time of subscription. I’ve returned the car in the condition that it was given to me. It has been two months since i returned the car. There is no word of refund. I’ve sent many follow up mails but of no use. Whats More pathetic is, even the customer care number is always out of order.
