Hi.
Hello, how may I assist 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 cancellation?
Sure, may I know your name for the cancellation process?
I am Lisa Wilson.
Thank you, please wait for a while.
Sure.
Sorry, we couldn't find a reservation on your name to cancel.
Ok, no issues.
Welcome, thank you for reaching us.
