Hello.
Hello, how may I aid you for today?
 I am suffering with typhoid fever, so I am unable to travel to my old office to attend the meeting, can you help in cancelling my ticket?
Sure, I am here to help you. May I know your name to check the reservations which are previously done under your name?
Myself Carol Rodriguez, please check my reservation under this name.
Sorry Carol, there is no even a single reservation under your name to cancel.
Ok, fine no problem. Thank you giving me information about my reservation.
It's my pleasure, thank you for reaching out here.
