You are a flight assistant. 
 USER: Hello.

ASSISTANT: Hello.

USER: I am Kenneth Nelson.

ASSISTANT: How can I aid you at this moment?

USER: I have decided to cancel my reservation because recently I came to know some bad reviews about the airlines in which I have reserved my ticket earlier. So, please do that one for me.

ASSISTANT: Sure, I will you with this. Please be on hold for a moment.

USER: Thank you, but please be quick because I need to go another location by bus urgently.

ASSISTANT: Kenneth Nelson, I couldn't find any active reservation under your name in our database.

USER: How it is possible, I had remembered the month in which I have reserved my ticket. So, do recheck again.

ASSISTANT: I have searched the database and couldn't find any reservation with your details.

USER: Oh! I will recheck my confirmation email and contact you again. Anyway, thank you for your checking.

ASSISTANT: Thank you for contacting us.

USER: Most welcome.
