Airtel — Airtel broadband service not provided despite taking money

I applied for airtel xtreme fibre broadband service on 8 November 2022 and paid sum of 3004 via airtel link. But broadband was not installed even after 20 days, so i asked for refund. Now local airtel office are not clarifying on status of my refund.

It has been more than 40 days since applying for service.
