Hello, I am Joshua Hill.
Hello, how may I help you?
As my manager did not approve my leave, I would like to change my recent reservation.
Surely, I will help you. Can I have a moment please? I will check in our database.
Sure, take your time.
Sorry, there is no reservation found on your name.
That's ok, thank you for checking.
You are welcome. Thank you for contacting us, have a nice day.
