Hello, I am Frank Carter.
Hello Frank, how can I help you?
As my manager did not approve my leave, I would like to change my recent reservation.
Sure, I will help you. Please wait, I will check your reservation status and let you know.
Sure, take your time.
Frank, I have not found any reservation under your name in our database.
That's ok, thank you for checking.
You are welcome and thank you for choosing us.
