Hello.
How may I assist you today?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, may I know your name for the changing process?
Sure, myself Mark Wilson.
Sorry as per your concern I can not amend your reservation as your reservation is not found as per our records.
That's ok, thank you for checking.
