Hi.
Hello, how can I assist you now?
 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, I will help you with that.
Thank you.
May I know your good name?
Rebecca Harris here.
Thank you for waiting, sorry there is no reservation found on your name in our system data to change it.
No issue, Thank you for the information.
Thank you for visiting us, we hope see you again.
