Hello.
Hello, how can I assist you?
Myself Gregory Turner. I want to change an existing reservation, please help out.
Sure, I can help you in that one. Please wait for a while to check your status.
Ok, take your time.
I have checked as per your request in our previous list but I am unable to find your ticket booking in our list to modify it.
Its ok, no problem. Thank you for your information on my request.
You are welcome and have a nice day.
