Hi.
Hello. How can I help you?
I made a reservation earlier this week to give a seminar but due to weather conditions I need to change it, will you help me in that?
Ok, may I know your name?
My name is Jennifer Miller.
 Please wait I will revert you.
Sure.
Sorry, no reservation was found on your name.
Ok, no problem. Thank you.
Thank you for availing us.
