Hello.
Hello, how may I help you?
Myself Carol Campbell. I made a reservation earlier this week to give a seminar, but my seminar has been postponed. Will you help me in changing  the reservation?
Sure, we are perky to help you.
Thank you for accepting my request.
Please be on hold. There is no reservation found on your name in our database.
Ok, not an issue. Thank you for your information.
