Hello.
Hello, how can I help you?
Actually my project final submission dates are postponed, so that I want to change an existing reservation. Can you help me?
Sure, can you please provide me your name for checking your reservation status in our database?
Sure, I am Lisa Nelson here.
Thank you, please be on line for a moment.
Ok.
Sorry Nelson, I  have not found any reservation by your name in our database.
Ok, no problem, I will check any other way. Thank you for your information.
Thank you for contacting us and have a nice day.
