Hi.
Hello, how can I assist you for the day?
Due to sudden change of my business meeting because of some technical problem, I need to change my reservation so can you help me with that?
May, I know your good name?
I am Deborah Phillips.
Please wait for a moment.
Sure.
Sorry, we found no reservation on your given name.
No problem, thank you for the information.
