Hello.
Hello, how may I serve 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 will try to amend your reservation. May I know the name on which ticket was reserved?
Sure, myself Elizabeth Carter.
Sorry, there is no reservation existing on your given name.
That's ok, thank you for checking.
You are welcome, have a nice day.
