Hi.
Hello, how can I address you?
I have booked a flight to attend a function. It was postponed so that I want it to cancel.
Sure, we are here to help you out. To proceed further, may I know your name please?
I am Charles Lewis.
OK, Charles Lewis, Please wait for a moment.
OK.
Thanks for waiting. Sorry, no reservation is found based on your name.
OK, no problem. Thank you for your response.
Thanks for approaching us. Have a nice day.
