ASSISTANT: Hello. Yes, you are at right place. How can I assist you at this moment?

USER: I need to cancel a reservation I recently made. It would be under Kimberly Nelson.

ASSISTANT: Ok Nelson, I will help you with cancelling the reservation if it is existing. Please be hold on for a while, I will check whether the reservation has existing or not. Thank you for waiting. Sorry Nelson, I did not came across your name in the reservation list to cancel your reservation.

USER: I see, my mother must have done so for me. Thanks for checking.
