Hello, how can I assist you today?

Actually, I reserved my flight ticket before one month back to travel to New York, but unfortunately my plan has been postponed. So can you help me to change this reservation?
user
Sure, just wait for a while. Can I know your name?
assistant
I am William Gonzalez.
user
William, there is no reservation found with your name in our records to change.
assistant
Thanks for your checking.
