Hello.
Hello. How may I guide you?
I am planning to cancel my recent reservation, due to health issue. Can you please cancel my ticket?
Sure, I can help you and on whose name the flight ticket has booked previously?
Thank you. My name is David Nelson.
Please wait for a while to check it.
Sure.
 Thank you for waiting, I have checked in reservation list to cancel your ticket but could not find any reservation with your name.
That's fine, thank you for your service.
Thank you for consulting our agency and have a nice day.
