ASSISTANT: Hello, how may I aid you for today?

USER: Myself Paul Phillips. As I have fallen sick, due to bad weather I would like to cancel my recent reservation, will you help me with that?

ASSISTANT: Sure, I am glad to help you with that Paul.

USER: Thank you for accepting my request.

ASSISTANT: Sorry to say this Paul, there are no active reservations with your name to cancel.

USER: Ok, no issues. My brother might have cancelled my reservation. Thank you for your information.

ASSISTANT: Yes, it might be the reason. Thank you for reaching out here.
