Hi.
Hello, how may I assist you?
I made a reservation earlier this week to give a seminar, but my seminar has been postponed. Can you please modify my reservation?
Sure, may I know your name to modify your reservation?
I am Mark Taylor.
Please wait a minute, I will check and get back to you.
Ok.
Sorry, there is no reservation found on your name.
Ok, no problem. Thank you.
Thank you for opting us.
