Hi.
Hello, how may I serve you today?
Actually I made a earlier reservation to go for a trip with my friends, but heavy work load in office I want to change my reservation.
Sure, I am here to help you with this. May I know your good name please?
George Young is my name.
Please wait for a moment.
Ok.
Sorry Young, there is no reservation found as per your name to change it.
That's ok. Thank you.
You are welcome.
