Hello. How may I help you today?
assistant
I reserved a ticket previously to meet my friend who was staying in New York but my friend was not staying in New York now, so that I want to change an existing reservation.
user
Sure, I am here to help you before proceeding may I know your name?
assistant
Please check with name Kathleen Gonzalez because previously I reserved with this name only.
user
Thanks for giving your name, please wait a moment.
assistant
Sure.
user
Thanks for your time, there is no reservation existed on your name.
assistant
It. It's not a problem. Thank you for checking.
user
Welcome, have a nice day.
