Cleartrip — cleartrip no refund after cancellation of air-ticket

On jan 2019, i did a flight booking through cleartrip (Id[protected]). Requested for a cancellation well in advance. We contacted customer support after a month and they said they are waiting for the airline to refund them. We checked with the airline by providing pnr and they gave us a screenshot where it shows full refund was done next day after the cleartrip request for cancellation came. We have been sending multiple emails to cleartrip, 4 months passed with no response. Kindly help resolve the matter.
