Hello.
Hello. How can I aid you today?
Actually I have planned to attend the client meeting but due to some technical issues the meeting has been postponed.
Ok.
Can you please assist me to change my reservation on the name of Anna Thompson?
Sure. Please wait for a while.
Sure.
Sorry  Anna Thompson, no reservation found on your name in our reservation list.
That's Ok, thanks for your help.
Thank you for choosing us, have a nice day.
