GoAir — Change of name on flight ticket.

Dear Sir,

I have booked tickets from PAYTM. My flight is from Mumbai to Bengaluru on 17th Nov 2022.

Flight PNR number is NCZ9GQ.
I want to change the first name of the passenger with name Punmiya Bharat Jain.

The first name must be changed to Punit. So, the actual name will be Mr. Punit Bharat Jain.

Please do the needful as soon as possible. Thanking you !!
