Cleartrip — Not providing refund or reissuing open ticket

I booked my flight ticket as of 29th February 2020 via the cleartrip website for a total payment of IN 62, 126.64/- Trip ID:[protected]. the flight was supposed to depart on and as of August 5th 2020, Kochi to New Delhi (Flight-Vistara UK 886), August 6th 2020, New Delhi to London, UK (Flight – British Airways BA 142), August 6th 2020, London, the U.K. to Calgary, Canada (Flight-American Airlines AA 6225). the airlines cancelled the trip due to covid and on asking refund, cleartrip issued a open ticket valid till march 31st 2022. The airlines till date is not operating this route. Hence cleartrip is not able to reissue the ticket. Cleartrip is neither issuing refund nor reissuing the open ticket, or extending the validity of the open ticket which is about to expire. They are also not responding to emails and hung up my follow up calls multiple times.
