purchased theme is wrong

Hello Guys,
I have a situation here…The theme that i purchased from Envato is this- https://themeforest.net/item/industry-industrial-business-wordpress-theme/20399753

On downloading it, what i got is this- http://aditech.adu360.com/

It is totally different from what i have paid for. I am in deep trouble as i have a deadline to meet. Author of this theme is ThemeKalia. I have contacted their support team 3 days ago but no response so far. When i posted it in public comment i got response that their team will contact but no one contacted so far. Any suggestion guy for a situation like this when i am on the verge of loosing this client for ever for no fault of mine…
