Hello. How can I assist you at this moment?

I am trying to change my recent reservation because my health is not good, so I am unable to catch the flight. Can you help me in changing the ticket?
user
Sure, I will help you with that. Can I have your good name for checking an existence of reservation?

My past ticket is reserved with name Dennis Campbell.
user
Ok Dennis, please wait a moment.

Ok, take your time.
user
Thank you for waiting. Sorry Dennis, there is no reservation found under your name.
