Hi, I am Sandra Lee.
Hello, how can I help you today?
As I am not issued with leave during my journey period, so I want to change my existing reservation. Can you please me with it?
Ok, please wait a moment I will check and get back to you.
Sure.
Sorry to say, no reservation found with your name.
That's fine, thank you for the response.
Thanks for reaching us, have a good day.
