Hello, I am Pamela Adams.
Hello, how may I aid 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. Can you please wait for a moment.
Sure, take your time.
Sorry, there is no reservation existing on your name.
That's ok, thank you for checking.
You are welcome. Thank you for reaching us, have a nice day.
