HappyEasyGo — Unable to contact customer to process or get updates on refund

Hello,

I booked a flight from Chennai to Hyderabad (Indigo 6E562) on Aug 18 2022 for 2 pax. Due to some unfortunate circumstances I had to cancel the ticket on 15th Oct.
Since then I am trying to contact HappyEasyGo customer care and it has been very frustrating to get no response even after trying via all communication channels possible.

Flight details:
IndiGo 6E562

Travel date: 21 Oct
Passengers: 2
Total refund amount: Rs 7728
Booking reference/PNR: QQKFGD
Order ID:[protected]

Any help in getting our refund will be highly appreciated. Thank you
