Hi. I am Ronald Martin.
Hello, how can I provide assistance to you?
I need to change my reservation, because my plan has changed recently. Can you assist me in that?

OK.
Thanks for giving your valuable time.
OK.
I have checked in reservation list to change your ticket, but could not find any reservation with your name.
That's ok, not a big problem. Thanks for your response.
