Hello.
Hello, How may I assist you?
Last week I have booked a ticket to attend a meeting at Boston but now I have got a mail that the meeting is going to be help at Charlotte, can you please change my existing reservation?
Sure, May I know your name?
Sure, I am Brandon Roberts.
Please give a minute.
Sure.
Sorry, No reservation found on your name.
Ok, may be it was not reserved properly. Thank you for your information.
Thank you, Have a great day.
