Air India — refund required for extra legroom seats pnr yrs0f

The pre-booked seat (Paid 60 aud) was not allocated to me in the ongoing flight sydney — delhi (Ai 301, 9th nov 2019). Attached is the boarding pass of non-extra legroom seat that was allocated to me at sydney airport.

Also attached is the receipt of the pre-booking.

It has been over two weeks since i contacted the airline and sent them the proofs via email, however, no one has acknowledged the email or sent a response

Horrible customer service! I feel cheated!
