Hello.
Hello, how can I guide you for today?
Robert Martin  here. I will be cancelling my reservation which I have booked few weeks ago due to my office work, can you please help me?
Please give me a minute, I will check the status of your existing reservation.
Ok, let me know my previous booking status after checking.
Sorry, there is no reservation found under your name in our database.
