Hello.
Hello, how may I help you?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I am willing to help you for this. Could you please share me your name?
Myself Charles Lee.
Please wait for a while, let me check the reservation status.
Sure, take your time.
Sorry to intimate that, no reservation is found with your criteria.
That's ok, thank you for checking.
You are most welcome.
