Hi, my name is Donald baker.
Hello, how can I help you?
Due to the sudden demise of my granny, I am unable to catch the flight. So I had a request to you to cancel my recent reservation?
Sure, please wait for a moment.
Ok.
Thanks for waiting, I found a reservation on your name, shall I cancel the ticket?
Yes, you can proceed to cancel.
Ok. Your reservation has been cancelled.
