Hello, I am Susan Moore.
Hello, how may I serve you at this moment?
As my manager did not approve my leave, I would like to cancel my recent reservation. Can you aid me with this?
Sure, I will render you. Please let me a moment to check the reservation list.
Sure, take your time.
Sorry, there is no reservation existing on your given name.
That's ok, thank you for checking.
You are welcome, have a nice day.
