Kpn Travels — Travel booking cancelled but Refund not initiated even after 20days

Dear Sir,
I have booked ticket on 26.04.2024 to travel from Ooty to Chennai (Date of travel: 12.05.2024). On the date of travel, i received a call from KPN ooty (Raj Kumar) informing that the vehicle has breakdown, so asked to arrange alternate mode and also he said that the refund will be initiated soon against the cancelled ticket.
But no message from KPN via SMS or email on this matter.
No refund also initiated till date.No response from head office [protected] when reached, No response even after sharing details and requested in watsapp.
Only the Ooty kpn incharge Raj kumar attending my call and responding, however my problem is not resolved till now.
Request you to immediately look into this matter and release my refund amount Rs 13, 524 (Rs 5670 + Rs 7854) at the earliest.I require this amount urgently for my personal needs.
Regards,
Ramadevi
