Hello, I am Catherine Mitchell.
Hello, how may I serve you at this moment?
As my manager did not approve my leave, I would like to change my recent reservation. Can you aid me with this?
Sure, I will help you. Please wait for a moment.
Thank you. Sure, take your time.
Sorry, there is n reservation existing on your name.
That's ok, thank you for checking.
You are welcome, have a nice day.
