Hi.
Hello. How may I aid you?
I want to change my reservation because my mother is not well, can you please help me out?
Sure, may I know on which name the ticket was booked?
Sure, my name is Dorothy Miller.
Ok, please hold on for a moment.
Sure.
Sorry, I could not find any ticket booked with your name.
No problem, anyway thank you for the information.
Thank you, have a nice day.
