Purchased a theme and not as advertised totally

I just purchased this edmento wordpress theme for $ 61 US and expected it as in the demo, just to find c#$%^&. And the theme author wont reply my ticket to this moment.
Advise me what should I do?

That theme has a one-click demo install feature. Have you checked the documentation that came with it? Of course, keep in mind that demo images are not included, per the item’s description:

Please note that none of the images used are included in the final package and are just for the preview purpose.

If you’ve ‘just’ bought it then best to give them some time to respond… a lot of authors may keep specific business hours, hours that might not include the weekends.
