Sorry to hear about such a bad experience.
To begin with your support requests. We located only three from you, none was related to any customizing or code modifications. You had two, which are related to PSD files and one where you asked how to change your logo from theme options.
!important rule serves to overwrite default CSS styles and it's not related to our theme, or any other for that matter, it's related to hierarchy in reading CSS on a web page. You should add !important rule to be certain that some CSS rule will be overwritten by yours. Otherwise, this rule is not necessary.
You can read more about that here - https://stackoverflow.com/questions/9245353/what-does-important-mean-in-css
Having that said, if you still have any doubts related to theme files, functions or file structure, please submit new ticket and one of our support staff will lend you a hand.
Hoping you could reconsider this poor rating. Thank you in advance.
