Jetpack doesn’t affect the way the comments are displayed. It will change the look at the comment form, but the comments themselves are controlled by your theme.
I would recommend that you check your theme’s comments.php and functions.php files, and compare the comment functions with one of the default themes, like Twenty Twelve:

http://core.trac.wordpress.org/browser/trunk/wp-content/themes/twentytwelve/comments.php#L36

I’m currently using Jet-Pack’s comment form but the comments are not showing up anywhere. They all show up whenever I reactivate my old theme. Even the newly posted ones.
