Hello.
How can I amend you at this moment?
I already book a flight ticket, but due to my bad health I am unable to travel. Can you cancel my reservation?
Sure, I would be helpful to serve you.
Thank you.
Before proceeding to cancel your previous reservation, may I know your name?
My name is Janet Harris.
Ok, please wait a moment.
Sure.
Sorry, based on your name we haven't found any previous flight reservation in airline database.
Ok, thank you for the information.
