Hello, I am Jessica Lewis.
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.
Surely, I will help you. Please give me a while, I will check and get back to you.
Ok, take your time.
Sorry, there is no reservation found on your given name.
That's ok, thank you for checking.
You are welcome. Thank you for reaching us, have a nice day.
