Hello, I am Robert Wilson.
Hello Wilson, how can I assist you today?
As my manager did not approved my leave, so I would like to cancel my ticket.
Sure, let me check your reservation status in our database.
Ok, take your time.
Wilson, I have not found any reservation by your name in our database.
That's ok, may be my brother has cancelled it before. Thank you.
You are welcome, have a nice day.
