Well, there’s a lot of code you’ve posted and the reason for the problem is pretty easy to fix (but hard to find).
You have this line in your code:
add_action('save-post','ktechs_save_contact_email_data');
But there is no hook called save-post. It should be save_post. So change the line above to
add_action('save_post', 'ktechs_save_contact_email_data' );
and it should work like a charm.
