Hi donniam
Please note that there is an audible notification of a new chat when you are logged in. Did you not hear the sound when someone was trying to initiate a chat with you? The title bar of the browser also dynamically changes to try and catch your attention as well, therefore there are two notifications in the free version of a new chat. The only difference with the pro version in this regard is that you receive an email notification of a new chat.
With regards to you mentioning “useless without buying”, I disagree. We have made this plugin fully functional in terms of chatting directly with your website visitor. It seems quite harsh that you would call the plugin “useless” without getting in touch with us first to find out what you weren’t getting chat notifications.
Furthermore, what do you mean by “two week trial”?
Kind regards
Nick
