HDFC Bank — RE:Money deducted but ticket not booked.

My Transaction was successful and payment went through but ticket was not booked, its showing cancelled and i have not recieved any Confirmation regarding refund. I emailed IRCTC and they said "transaction was a settlement-failed transaction for which no amount was debited towards IRCTC. That is we did not receive any payment authorization from your bankers to book the ticket.Requested to please contact to your bank"

Please look into it as soon as possible

Thanks,
