Hello, how may I help you?
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?
Sure, I am happy to help you. Can you please let me know your good name?
I am Susan Mitchell.
Sorry, there is no active reservation on your name in our records.
No problem, thank you for the information.
