Hi.
Hello, how may I assist you today?
I am not feeling good to travel by flight so, I have decided to go by road. Please cancel my recent reservation.
Sure, may I know your name to check the reservation in  the reservation list.
Ok, Kathleen Gonzalez is my name.
Please wait for a moment.
OK.
Thank you for waiting, there is no reservation found on your name.
That's ok, not a problem. Thanks for the response.
Thank you.
