Hello, I am Dennis Anderson.
Hello, how may I help you at this moment?
As my manager did not approve my leave, I would like to cancel my recent reservation.
Sure, I will help you. Please wait for a while.
Sure, take your time.
Sorry Dennis, there is no reservation found on your name.
That's ok, thank you for checking. It might be cancelled before.
You are welcome. Thank you for reaching us, have a nice day.
