Hello.
Hello, how may I assist you today?
Can you help me to modify the reservation which I had did a week ago?
Sure, may I know your name for the changing process?
Ok, please check for the name Robert Carter.
Sorry, as per your concern I can not amend your reservation, as your reservation is not found as per our records.
Ok, that is not a problem. Thank you for assisting me.
Welcome, thank you for reaching us.
