Hello. I am Scott Taylor.
Hello. How can I aid you today?
I have reserved a flight in the past week to attend a business meeting but suddenly I got a call from my manager and informed that the meeting got postponed, can you please help me in  ticket modification process?
Ok, I will help you with that.
Thank you for accepting my request.
Please wait for a minute.
Sure.
Sorry to say that, there is no reservation found on name in our database.
How can you say that my flight ticket booking has not found? I have booking confirmation mail, can you please recheck once?
Ok, I have rechecked based on your name there is no reservation found in our database.
Ok, that's fine. I think it might be some technical problem while I was booking the ticket. Thank you for your response.
Thank you for consulting us. Have a nice day.
