Refund confirmed to Happyeasygo account by Air India (RA Number : 5854872)

I booked a flight ( for three passenger) from Durgapur to Hyderabad from HappyEasyGo . The flight was cancelled by Air India and I generated a refund request. The airlines told me they have processed the refund in their account( Air India given refund reference RA Number: 5854872 . But they have not yet provided me with the refund. And whenever I call they ask me to wait for 45-90 days. How much time do they need to credit it in my account. I submitted all document requested by happyeasygo.
Please help my case
