HappyEasyGo — Refund not received

I have been chasing happyeasygo since last 35 days and even though they accept that the airline has refunded the amount but the amount has been stuck with them. I have repeatedly calling them and every time they reply with new deadline and have been rude in answering about money.
I am real stuck with that fraud platform and i now started doubting about their actual intention to even refund my money.
My complaint no with the happyeasygo is 90492052
E-ticket no.[protected]
Date of cancellation: 02/12/2021
Booking date: 25/11/2021

Full amount has been refunded by the airline & they confirmed it too on 6/12/21
