We need refund back for E TICKET number[protected] under the name of Kunal Sawhney. At that time(8th July 2020) air India consultant told me PNR is already cancelled but we didn’t get our refund back in account. we called them 50 60 times after it but they sometimes response and then after listening they put phone on hold or either hang up.
my ticket is on 20th April from sydney australia to delhi airport.

looking forward from you.
