Hello, I am Angela Walker.
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. Can you please share your travelling dates?
First check with my reservation.
Sorry, there is no reservation available on your name.
That's ok, thank you for checking.
You are welcome. Thank you for reaching us, have a nice day.
