Travolook — Refund of fund

I booked a ticket from cochin to bhubaneswar on 02 Oct 21 by travolook. My amount got deducted but the ticket didn't confirm. Travolook sent me a message regarding cancelation of my ticket due to pnr number not generating. They sent me a message for refund the fund within 7 days. But I didn't get refund till yet. The reference number sent by travolook is REF[protected]. The screenshot has been attached with the mail for your kind reference.
