Hello, I am William Thompson.
Hello William, how can I help you today?
As my manager did not approve my leave, I would like to cancel my reservation.
Sure, I am here to help you with that, please hold on for a moment to check your reservation status.
Ok, take your time.
William, I did not find any active reservation with your name in my database.
That's ok, may be it might be cancelled before.
Thank you for reaching us.
