Trujet Airlines — Ticket refund amount not received

Flight 2T517 was cancelled by Trujet on 05/03/2022.

But refund towards the full ticket fare paid of Rs. 14220/- is not received.

I have emailed them multiple times upto apalette authority level. But no response. Over phone they say servers are down so could not do anything. I need refund of fare + interest for 90days back to my same payment mode which was used to book ticket.

Ticket PNR Booking number: C2A8N4
