Hello.
Hello. How may I assist you today?
I have planned a trip to enjoy my holidays in my home town but suddenly there is an important meeting on the same dates, so can you please help me in flight ticket cancellation?
Sure, I am here to help you with that, please wait for a minute.
Thank you for considering my request  and I will wait.
May I know your name to proceed further?
Sure, my name is Stephen King.
Sorry, I could not find any reservation with your name in our database.
OK, not an issue with that one. I think the ticket booking is not done properly. Thank you for your information.
It's my pleasure.
