Hi.
Hello, how can I aid you today?
 I made a reservation earlier this week to give a seminar, but my seminar has been postponed. Can you please help me in changing my reservation?
Sure, we are here to help you. May I know your name?
I am Daniel Gonzalez.
Ok, wait for some time.
Sure.
Thanks for waiting there is no reservation found on your name.
That's ok, not an issue. Thank you for your information.
Thanks for approaching us.
