Cleartrip — not responding to calls and not refunded any amount

I booked flight tickets using the travel booking website cleartrip.com and by paying through internet banking, my account got debited but my tickets not got booked. They gave one link to track refund status but not provided any refund reference id.in the link it's showing that amount refunded but not credited to my account. Not at all responding to any calls though made calls a number of times. They just made me to wait almost 20 mon everytime and abruptly cut my call without attending any customer service representative.
