Hi.
Hello, How can I support you at this moment?
I am Kimberly Wilson.
Ok.
 Actually I made a earlier reservation to go for a trip with my friends, but heavy work load in office the trip has been postponed. So, help me in changing the reservation.
Sure, I can help you in that.
Ok.
Please wait, let me check your reservation status.
Sure.
Thanks for your time.
Fine.
Sorry Kimberly Wilson, there is no active reservation on your name to change it.
No problem. Thank you for your service.
Thanks for choosing us.
