Air India — Refund not received

I am waiting since May 2020. Now AirIndia saying we refunded your Ticket 2 months back . I did not receive any money. I chasing up last 2 months they made me go here and there, but no use. International airline regulatory body should make a note how this So called AirIndia harass people. They super fraud and super shameless people. I think to get job in AirIndia that test is one should be biggest shameless person. CUSTOMER care say you write to [protected]@airindia.in then next time they say go to website and leave feedback. All done 30 times. You getting reply we cannot help in case of website booking go to CUSTOMER care. They are ###. just cheating people typical Govt department. I thought Govt Department improved. Today AirIndia is Example.
