You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello, how may I aid you today?

USER: Myself Rachel Evans. I want to cancel my recent reservation due to some health issues, can you help me?

ASSISTANT: Sure, I am glad to help in cancelling the reservation. Please allow me a moment to check whether the reservation is found on your name or not.

USER: Ok, I will wait for your response.

ASSISTANT: Sorry Rachel Evans, there is no existing reservation on your name in our data base to cancel it.

USER: That's ok, no problem. May be my friend has been cancelled before and I am not aware of it. Anyway, thank you for the information.

ASSISTANT: Thank you for connecting with us.
