 I have to do some modification in my previous flight ticket booking that there is a sudden event held at my home town, so I am unable to travel the trip. can you please help me out with changing of my reservation?
Sure, I am here to help you. Can I have your good name please?

Ok, please wait for a while.
Ok.
Sorry to say that, there was no reservation found on your name to change it.
That's ok, thank you for your help.
