Hello. I am Gregory Lopez.
Hello, how may I amend you today?
Yesterday I have booked a ticket for Houston but your agent misplaced my origin code from Los Angeles to Boston. Can you please change my existing reservation?
Sure, please wait for a moment, I will check and revert to you.
Sure, I will wait.
Thank you for waiting, there is no reservation found on your name.
Ok, it's not an issue.
Thank you for making us to serve you.
