HappyEasyGo — Money not refunded after 90 days of flight cancellation

I booked a FREE CANCELLATION flight from Varanasi to Pune on 27th Oct 2022 for the date - 29th Nov 2022.
Due to some personal reasons I had to cancel the flight. I cancelled the flight on 27th Nov 2022.
Its been more than 3 months/90 days and still I have not received the refund money.
I have been constantly calling the helpline numbers(which is not working), sending emails, reaching out on instagram, twitter and still no response from them.

Please help me get my money back.
