HappyEasyGo — Refund for flight

Trip Id[protected]
Flight from Bangalore to Kanpur

Cancelled on 30 June 2022

According to happyeasygo website, it is mentioned
"Your refund request has been forwarded to the airline. Once received, the refund amount will be transferred to your account within 48 hours.
Due to high refund request volume, it takes about 45-90 days for airlines to process a refund request. Your patience during this time is highly appreciated. You can also contact the airline directly regarding the status of your refund"

It now more than 90 Days and I have not received the refund. I have called and email them multiple times but the response I get is that they require some more time to refund. But as a result I am not getting any refund.
