Ibibo Group / Goibibo — ticket confirmation

I have booked flight from delhi to toronto for aug 30. I have paid full payment of rs 71174.00. They have not yet confirmed the ticket. I called them around 15 times, they are only asking to wait for 2 hours then 4 hours then 1 day then 12 hours.
I have called many times, each time there is different agent and they all are saying different things. I tried to chat with them using their live assistance, but they are not willing to pass the information to related department.
They are just keeping the money from customers and are not willing to solve their problem. They are big cheat. The worst company to book the tickets.
