Hello.
Hello.
John Parker is my name.
How can I serve you?
I want to change my existing reservation for my health checkup in Atlanta, can you help me?
Sure. Please wait a  while.
Thank you for your positive response. Ok, I will be waiting for your reply.
Thank you for waiting, but I am sorry to say that, there is no active reservation found with your name in our database to change it.
Oh! That's very disappointing to hear from your side. Anyways, thank you for checking.
Thank you for opting us.
