HappyEasyGo — Not refunding from last 1 month even after airlines refunded the amount to their account

My flight from Raipur to Pune got cancelled due to runway closure in Pune.

I raised a refund request on 7th of October and I Indigo sent the refund amount to HappyEasyGo on 7th of October itself. The told they would take 15 working even days to patiently waited.
But even after 15 days they didn't refund the amount. Now it's more than a month. I have called their customer care many times and always I am getting the same response that money is not showing in there account. I really mentally tortured now.
They have been keeping the money interest free and using my money, god know for what purpose. I can see a lot of complaints against them regarding the same issue.
