Hello.
Hello, welcome to NFC agency. How can I help you?
Actually I had a business meeting in DTW,  but my manager had changed the dates of the meeting. So I need to modify my existing reservation, can you help me?
Sure, could you provide me your name?
My previous reservation is done with the name Jerry Gonzalez.
Ok, please wait for a minute.
Ok.
Sorry Jerry, no reservation found on your name.
It's ok, thank you for your kind information.
Thank you for approaching us.
