How can I help you John?

As my meeting got postponed, I would like to change my existing reservation. Can you help me with this?

Sure, I will help you with that. Please wait for a while. Sorry Jones, there is no reservation found under your name.

Take your own time. Ok, not an issue. May be something went wrong while booking the ticket.
