Hi.
Hello, how may I serve you?
I made a reservation earlier this week to give a seminar but due to weather conditions I need to cancel it,. Can you help  me in cancellation?
Sure, may I know your good name?
I am Raymond Allen.
Please wait for a minute.
Ok.
There is no reservation found with your name.
That's ok, thanks for your information.
Thank you for availing us.
