Hi.
Hello.
My name is Kenneth Walker.
Walker, how may I help you?
My business meeting has been postponed, so I would like to change my existing reservation.
Sure, I will help you in that. Please wait, let me check your reservation status in our database.
Ok, please make it fast.
Sorry, there is no reservation under your name in our database.
That's fine, no problem.
You are welcome and have a nice day.
