Hello.
Hello, how can I assist you today?
I am Gary Mitchell.
Ok.
I made a reservation earlier this week to give a seminar, but my seminar has been postponed. Please change my existing reservation.
Sure, I will help you with that.
Ok.
Please wait a while.
Ok, I will.
Thank you for waiting. I have checked in reservation list to change your ticket, but could not find any reservation with your name.
No issues, thank you.
Thank you for choosing us.
