Hello.
Hello. How can I help you today?
Can you please help me in changing my existing reservation, as my health is not good?
Sure, I am here to help you with that, can I know your good name to proceed further?
Thank you for the response, my name is Robert Gonzalez.
 I am very sorry to inform you that there is no reservation found under your name in our database.
Ok, not an issue. Anyways, thank you for the information.
Thank you for reaching us.
