Hi. Shirley Perez here.

Hello, how may I help you?
assistant
I request you to change the flight reservation as I wish to change the time or date, so can you look into my previous booking, and change to another available flight on the preferred time or date.
user
Sure, please wait a moment I will check the details and revert you.
assistant
Ok, let me know once the checking the is done.
user
Sorry Perez, I did not found any reservation on your name.
assistant
Ok, it is not a problem.
