HappyEasyGo — Happy EasyGo - Pending the refund for last 7.5 months

Address:

India

Respected Sir/Madam,
I have booked a flight ticket (7 passengers) for AirIndia through 'Happy EasyGo' portal but I have cancelled the ticket due to Lockdown. (Srinagar to Delhi and Delhi to Hyderabad Pune). Order ID: [protected], PNR: Y2053

I raised a refund request in HappyEasyGo on 10th of April itself, it's been 7.5 months but still, it is pending. They told would take 45-90 working days max. Now it's more than 7.5 months (215 days). I have called their customer care many times and also emailed (copies attached) them several times and always I am getting the same response that we are working with airlines and need some more time to resolve. I am really mentally tortured chasing Happy EasyGo for the last 7 months for the refund but I am not getting a satisfactory answer from their team.
Please help me to get my refund as soon as possible
