Hello.
Hello, may I know  your name?
I am Kimberly Scott, I made a reservation earlier this week to attend my friend marriage. Unfortunately marriage got postponed so, I want to change my existing reservation.
Please, wait for a while.
Sure.
Thank you for waiting. As I checked with the storage data there is no reservation found on your name.
OK, not a problem. Thanks for your time.
