Hello, I am Virginia Walker.
Hello, how may I serve you?
As my manager did not approve my leave, I would like to change my recent existing reservation.
Surely, I will help you. Can I have a moment to check your ticket's details?
Sure, take your time.
Sorry, there is no ticket showing on your name.
That's ok, thank you for checking.
You are welcome. Thank you for reaching us, have a nice day.
