Hello.
Hello, how may I aid you today?
I am Brandon Lee. I am planning to cancel my recent reservation, due to health issue. Can you please cancel my ticket?
Sure, I am here to help you out. Please allow me a moment.
Thank you. Sure, I will wait for your reply.
Sorry  Brandon Lee, there is no active reservation on your name in our database.
