Hello.
Hello. How may I help you?
Myself Elizabeth Wright. I am going to change my existing reservation. Can you please help me for this?
Sure.
Ok, I will wait for your response.
Wait for a moment please. I will check and get back to you.
Sure.
Thanks for waiting. But I am sorry to say that there is no flight reservation on your name to change it.
Not a big problem, anyhow thank you very much for your service.
Thank you.
