Hi.
Hello, how can I assist 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 here to help you. May I know your name to check with existing reservation?
I am Justin Wilson.
I am sorry to say you that there is no reservation found under your name in our database.
No problem, thanks for the information.
Thank you for choosing us.
