Hello.
Hello.
Myself Kevin Green.
How may I aid you?
Due to some business seminar meeting, I am going to change my existing reservation. Can you please help me for this?
Sure, I am here to help you out.
Thank you for that.
 Kevin Green, we haven't found any reservation under your name in our database.
Not a big deal, anyhow thank you very much for your service.
Thank you for approaching us.
