Hi.
Hello. How may I serve you today?
Can you help me in changing my recent reservation, as my exam is postponed?
Sure, I'll try to change an existing reservation. Can I have your name please?
I am Larry Evans.
Ok, please wait a moment.
Sure.
Thank you for waiting, I have checked in reservation list to change your ticket, but could not find any reservation with your name.
That's ok, thank you.
Thank you for approaching us.
