Hi.
Hello, What kind of help are you expecting from our side?
 I made a reservation earlier this week to give a seminar, but my seminar has been postponed. Can you please help me in changing my reservation?
Sure, I can change your reservation right now. Before that I need to know your good name please?
I am Gregory Brown.
Ok, wait for some time I will check the reservation on your name and get back to you.
Sure.
We are sorry to say that, there is no active reservation found on your name.
Ok, not an issue. Thank you for checking.
Thanks for approaching us.
