Indigo Airlines — Ticket Booking and cancelled automatically

I've booked a ticket from mumbai to trivandrum. And my payment also successful the air fare was debitted from my bank account. But within a few minutes from payment i got a mail from indigo airlines that my ticket was cancelled but i didn't cancelled they have automatically cancelled my ticket. If i try to contact indigo customer care no any response. I've spent around 150 mins in indigo customer care but no any response. I've mailed to indigo customer care also in mail also there is no response. i got only the automatic reply mail only. I tried through facebook also to contact indigo. In that also there is no any response. Kindly help in this.
