Hi.
Hello.
I am William Adams.
How can I aid you?
 I made a reservation earlier this week to give a seminar, but my seminar has been postponed.
Ok.
Can you please help me in that?
Sure.
Thank you.
Wait for a while.
Sure.
Thanks for waiting.
Ok.
There is no reservation found on your name.
No problem, thank you for the information.
Thank you.
