Hello, how may I help you today?
assistant
I am Donna Anderson. 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 to the trip. Can you please help me out with changing of my reservation?
user
Sure, I am here to help you with this. Sorry Donna, there is no reservation found as per your name to modify it.
assistant
That's fine, thanks for your valuable information.
