Volercars — not refunding money

Address: Gurgaon, Haryana

I booked a car, 15 days in advance i made full payment.
On the day of the delivery of the car, the told due to mechanical issues they cannot provide the car, they promised to refund the entire booking amount (Rs. 10, 500). It has been a month, but due to "technical issues" they yet haven't refunded despite calling them and emailing them multiple times. Their only respnse is we will inform you once we initiate it. They dont provide any arn /prn numbers that we can cross verify with banks that can allow us to kno what techniical errors occured. All they do is expect us to stay mum and not bother them. Voler is a big cheat. Fraud. Indespicable.
