HappyEasyGo — Not refunding the money of cancelled flight

My go first flight was cancelled by the airline for 4th July 2022 but the refund has not happened.
Go Air have confirmed that the refund was done on the same day but happy easy go is not refunding the money.
They even shared the screenshot of the refund done.
We have been trying to reach out to HappyEasyGo customer care with almost 100+ emails exchanged.
All they reply is they are not in position to update by when this can be resolved.
And customer care has stopped picking up the calls
