MakeMyTrip.com — Ticket not issued but amount deducted from my bank account

I made a booking on MAKEMY TRIP.COM on 12th March - 2015 for my daughter to travel from Chennai to Singapore (Booking ID no - IN1503B9S082870 ).Although the ticket amount ( Rs.10, 311) was debited from my axis bank account, the E-ticket was not automatically issued by mail . When I made complaint on 13th March over phone, I was told the money will be credited back to my bank account within 72 hours and the case was registered under reference ID :[protected]. Till today, I haven't received any positive response from MAKEMY TRIP office with regard to refund in spite several follow up phone calls and e-mails. It is really frustrating to digest the lukewarm response from MAKEMY TRIP office in addressing customer complaints .
