Hi, I am George Turner.
Hello, what can I do for you?
 I made a reservation earlier this week to give a seminar but due to weather conditions I need to change the dates. Can you help me with this?
Sure, please wait a minute. I will check and get back to you.
Ok.
Thank you for your time. Unfortunately there is no reservation found according to your reservation.
Ok, not an issue. Thanks for your information.
