Vahathi Motors Driving School — Not provided service, not being issued refund

I was promised driving classes daily morning from 7-9 am. On the first day, instructor came 30 minutes late. Entire rest of the week, nobody came for classes. When I spoke to the agency, every day they gave new excuses. I received no prior intimation of cancelled classes on any of the days. Everyday I would get ready and wait but nobody comes to take classes. I requested a refund a week back but the agency is not responding to my query ever since I asked for a refund.
