Cleartrip — refund against my pune ticket

Website:

cleartrip.com

I have booked a flight on 27 july 2018 for 10 aug for pune to patna. Trip id is[protected]... But they has not refund my amount 4593 still... For this i have called at least 50 times to them. They are only passed it to my bank.. Which is not appropriate as i have called my bank too they are saying that they have not recieved any amount from cleartrip. So, why they would hold. These guys are passing the ball only. So they wud be stay in safe zone.
