Yatra Online / Yatratrip.in — Refund not received against cancellation

I have cancelled 3 tickets out of a group booking on Yatra and after 8 days, I have still not received the refund. Also I paid extra cancellation charges for getting full refund incase of cancellations but Yatra asks me to claim the partial amount from directly from the insurance company which is a very lengthy process. They take the charges themselves but asks to claim and indulge in a long process with the insurance company. I want my additional cancellation charges to be refunded else I will file a case in the consumer forum. Yatra is not refunding the airline charges inspite of taking extra charges for full refund process. My reference number is[protected]
