Zoomcar — Repair Refund

I had to replace the battery on my Zoomcar during my last trip and I had informed the customer care center about the same and followed their instructions in sending videos and photos. I had paid for the repair and I was allowed to upload the bills for refund. But no action has been taken since. It has been two weeks since my trip was complete and the customer care email ID not responding despite several reminders. The customer care phone number is not taking me to an agent to talk about the issue as there is no current booking. There is no way to talk about old bookings on the customer care line.
