Hi.
Hello, how can I help you?
Owing to an emergency, my live concert got postponed, so I want you to change my existing reservation.
Sure, I am willing to help you for this. May I know your name please?
Sure, Gregory Moore here.
Just a moment, let me check your reservation status in our records.
Sure.
Sorry for inconvenience, no reservation is found under your name to change.
Ok, no issues.
Thank you very much for approaching our agency.
Thank you for your assistance.
You are welcome.
