Cannot Utilize all function – Support nonexistant

When trying to set up this theme I could not edit some of the function in the customizer. For whatever reason this theme and one other by the same author have the bottoms of all the screens cut off so that you cannot finish editing the theme. It renders the theme completely useless. I read on their page that if you wanted support for the theme that you should use the “Contact Us” sheet,so I did. I got a message back saying that they only give support for a member who has subscribed to them…Guess what?!?! you have to pay for the subscription. No thanks since the support sucks so badly.
