Hello.
Hello. How may I assist you?
 I am very interested to visit historical places in my holidays, so, I have booked a trip to visit some old temple to write a story on that. Can you cancel my ticket?
Sure. Please let me know your name.
My self Karen Wilson.
Karen, there is no reservation found with your details.
Ok, it's fine no problem, thanks for your valuable time in helping us.
You are welcome.
