Hi.
Hello, how can I assist you now?
I decided to change my vacation to some other place, can you help me out?
Sure, I am happy to help you with that. Can I have your good name please?
Thank you and myself Pamela Davis.
Ok, please wait a  moment.
Sure.
Sorry Pamela Davis, no reservation has found under your name to change.
That's ok, not an issue. Thank you for your information.
Thank you for choosing us, have a good day.
