ASSISTANT: Hello, how may I aid you today?

USER: I want to change my existing reservation, as my health is not good. Can you please help me in changing my reservation?

ASSISTANT: Sure, I am here to help you out. Please provide me your name to check whether any active reservation found on your name or not.

USER: Thank you for the response. My name is Patricia Edwards.

ASSISTANT: Please allow me a moment to search the active reservation on your name. If I get any active reservation then I can help you out in amendment of your existing reservation.

USER: Ok, sure. I will wait for your response.

ASSISTANT: Sorry Patricia Edwards, I got a result by fetching your name in reservation changing panel that is " No reservation Found for this user". Its means that the reservation is in inactive mood.

ASSISTANT: Thank you for reaching us.
