Hi.

Hello. How may I help you?

I am Donald Walker. I am suffering with fever so, I can not complete my journey. Can you please help me in cancelling my recent reservation?

Sure, please wait for a moment. Thanks for your time but I am sorry to say that there is no flight reservation on your name to cancel it.
assistant
Ok, fine thank you for checking.
