Hello.
Hello.
Myself John Jones.
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.
My pleasure, have a nice day.
