Hello. I am Stephen Smith.
Hello, how may I assist you?
I had planned to go on a trip, but it was postponed due to some reasons. Can you change my recent reservation?
Ok. Sure, I will help you with that.
Ok.
Thanks for waiting. But I am sorry to say that there is no flight reservation on your name to change it.
That's ok. Anyways, thank you for your help.
Thank you.
