Travolook — Ticket cancelled without any intermittent and didn't get refund

Address:

Gurugram, Haryana

I booked a flight ticket from Vijayawada to Bangalore on 12 sep 2021, and was promised to get a refund in 10 -12 working days. I kept calling them every week but they kept postponing the refund. They even went to extents of refusing to answer any calls from my number after making me wait for three months
causing irreparable mental strain. Kindly address my months long struggle to get my money back rightfully.
