Hi.
Hello, how may I assist you today?
Can you please change my recent reservation? As my planned trip has been postponed to some other dates.
Sure, may I know your name for the changing process?
Sure, my name is Helen Johnson.
Ok, please wait for a while.
Sure, take your own time.
Sorry, there was no reservation found with your given name.
