I want to change my existing reservation, my music concert got postponed. Can you please help me out with that?

Ok, may I know your name?

Thank you for accepting my request, I have reserved it on the name of David Harris.

Please hold on a moment.
assistant
Sure, take your time.

Thanks for waiting, I have gone through the reservation list twice but could not find any reservation active under your name.

Oh! I think the ticket was not booked due to server issue. Anyway, thank you for the information.
