Hi.
Hello, how may I help you?
 I need to cancel my reservation due to some personal issues. So can you help me with cancellation of my reservation?
Sure, I am here to help you with that, can I know your good name to proceed further?
I am Lisa Davis.
 I have checked in reservation list to cancel your ticket, but could not find any reservation with your name.
No problem, thanks for the information.
Thank you for reaching us.
