Html template rejected without any feedback from the reviewer, may you help us check what's wrong?

Hi there,
we wanted to get into themeforest world too and recently built thid html template: http://ift.tt/1Ugcwc6

Today it got rejected:
Unfortunately, after reviewing your item 'SwiftCard - Responsive One Page vCard Template' we found that it's too far off the standards we require, so you'll be unable to submit it again.

There's no feedback provided by the reviewer so we don't really know what's wrong with our template, any suggestion will be super appreciated
Thanks!
