I, vishal kohli would like to bring this to your kind notice that my ticket for the sector delhi-goa-delhi was scheduled for 5th august dep & return on 9th aug 2020 with pnr no o96zwj & gfiktr.
Flight was cancelled by the airline on 20th july.
It was a family trip and now looking into the current situation i don't want to get life of my family in danger by travelling our of state.
I need refund but goair has given credit shell.
I've lost my job in april due to covid and in urgent need of money to pay my dues.
