ASSISTANT: How may I aid you today from my end?

USER: I want to change my existing reservation because my cousin had booked my flight ticket incorrectly. So, can you amend my ticket?

ASSISTANT: Sure, I will certainly render you in modifying the flight as per your request.

USER: Thank you for accepting my concern.

ASSISTANT: Nicholas Campbell, please allow me a moment to check whether any active reservation is found on your name or not.

USER: Sure, I will wait for your response.

ASSISTANT: Sorry Nicholas Campbell, I didn't find any existing reservation on your name in our reservation portal.

USER: Can you please recheck the reservations which were done on the month of september as my cousin had reserved my flight ticket on that month?

ASSISTANT: In my search to your request, I got the same result that is "no reservation found for your user".

ASSISTANT: Ok Nicholas Campbell, please go through your cousin's email about this concern to get more clarity about the reservation. Thank you for reaching us, have a nice day.

USER: Sure, thank you for your expeditious service.
