Hello, I am Patricia Anderson.
Hello, how may I help you at this moment?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I will help you. Please wait for a moment.
Sure, take your time.
Sorry Anderson, there is no reservation existing on your name.
That's ok, thank you for checking.
You are welcome, have a nice day.
