Hello.
Hello, how can I aid you today?
Owing an emergency, I want to cancel my reservation. Can you help me for that?
Sure, I am here to help you. May I know on whose name the ticket has been reserved formerly?
Thank you. My name is Raymond Walker.
Sorry Raymond Walker, there are no flights reserved on your given name formerly.
That's ok, thank you for checking.
Welcome, thank you for choosing us. Have a great day.
