Indigo Airlines — clarification for ticket booking

Address: New Delhi, Delhi

I got my flight ticket booked from delhi to Pune on 1 st June and the money was deducted online via my SBI bank. But I m not sure whether my ticket is booked or not. I tried calling customer care and was on hold for more than 20 mins twice but no reply came as promised 6 mins waiting time. Service of indigo is pathetic and dismal. Even u can't pick up a call. I doubt whether u will help me on the subject matter...
