Air India Express — Flight Refund

I have called up air india executive to cancel my tickets booked for september 2021, booked on 4th september and cancelled on 5 september at 12 pm.

1. Without final confirmation ticket was cancelled. I am yet to recieved ticket cancelled mail from them
2 Even after cancellation after a wait time of 30 mins..the air india executive asks to fill feedback form.
3 tired filling form thrice, everytime I submit it says something went wrong.

Terrible that the customer care has denied to raise refund request but cancelled my ticket without final approval.

Please look into this matter looks like they are doing fraud with frequent flyer customer tooo
