Hello.
Hello, what can I help you for today?
Myself Kimberly Turner. I want to do some modification in my previous existing reservation, can you help me for that?
Sure, I  will definitely help you about it. Please give me a moment to check your existing reservation.
Sure, take your time.
Sorry Turner, I do not find any reservation under your name to change it.
That's ok, thank you for checking.
My pleasure, thank you for reaching out here. Hope you have a great day ahead.
