Hi.
Hello. How can I help you today?
Owing to an emergency, my meeting with client got cancelled, so I want you to cancel my recent reservation.
Sure, I am here to help you with that, can I know your good name to proceed further?
Sure, Pamela Miller here.
 I have checked in reservation list to cancel your ticket, but could not find any reservation with your name.
Ok, no issues. Thank you.
Thank you for reaching us.
