Hi. I am Shirley carter.
Hello, how may I help you?
I made a reservation earlier in the wrong date unknowingly. So, I want to change my existing reservation. Can you please help me in changing the reservation?
Sure, please wait for a minute.
Ok.
Thank you for waiting, there is no reservation found on your name in our airline database.
Ok, no problem. Thank you.
Thank you for choosing us.
