HappyEasyGo — I have not received my flight ticket refund yet. IT HAS BEEN MORE THAN THREE MONTHS

I had booked a flight ticket via happy easy go (SpiceJet, Kolkata to Pune for 12/08/2020). The flight was cancelled by the airlines and the money was refunded to happy easy go. I was told that I will be receiving my refund within 90 days, i.e by 26/11/2020. I still haven't got my money back even though I provided a screenshot by the airlines where they clearly mentioned that they refunded the money. I need my money back.
