Air India — Mislead and REFUND not received

Following are the chronicle of the event where Air India has not resolved my refund issue even after 5 months:
1. Ticket bought on May 4th, 2022, ticket attached and the number:[protected]
2. Paid on my Citibank credit card ending in 5167 for amount INR 106, 586
3. Cancelled the ticket in August 2022.
4. Followed up continuously for refund and finally Air India said they refunded on 10th of January, 2023 with txn ID: 098KUS74J51HX. Air India will not share the exact refund amount nor will they say whether they received a confirmation of receipt of refund txn from Citibank.
5. On the other hand, Citibank made me wait for 15 days, saying it can take up to 15 days to receive the refund. Now that it is not reflected on my card, Citibank says they can do nothing as Air india will not tell me the amount refunded and the correct 23 digit numeric refund txn ID.
6. I have emailed to Air India and now no response from Air India for the past 5 days.
