Kesari Tours — Regarding Go Air refund

We did Dalhausi Dharamshala Amritsar Tour on 1st June 23. We were 8 members. We paid full amount to kesari including airfare. Then before few days of tour we are asked to book air ticket by our own as go air airline had cancelled all its flights. We have been told that airline refund will return to us soon.
It's almost 6 months passed...we are waiting for the refund!!!
