Removing "date" "comments off" from posts

sorry to ask an oft-asked question, but I have read all the previous posts on the subject, and deleted a bunch of text from CSS (comments.php, archives.php etc), but still can’t make it work. I guess I need to run “Display: none” somewhere, but not sure where. I am running zeeBizzCard, by ThemeZee. Here is the comments.php code, which may or may not be relevant. My site.

<?php 

	if ( post_password_required()) { ?>
		<p><?php _e('Enter password to view comments.', 'themezee_lang'); ?></p>
	<?php return; } ?>

<!-- You can start editing here. -->

<?php if ( have_comments() ) : ?>

<div id="comments">
	<h3><?php comments_number(__('No comments', 'themezee_lang'),__('One comment','themezee_lang'),__('% comments','themezee_lang') );?></h3>

	<?php if ( get_comment_pages_count() > 1 ) : ?>
	<div class="comment_navi">
		<div class="alignleft"><?php previous_comments_link() ?></div>
		<div class="alignright"><?php next_comments_link() ?></div>
	</div>
	<div class="clear"></div>
	<?php endif; ?>

	<ol class="commentlist">
	<?php wp_list_comments( array('avatar_size' => 56)); ?>

	<div class="comment_navi">
		<div class="alignleft"><?php previous_comments_link() ?></div>
		<div class="alignright"><?php next_comments_link() ?></div>
	</div>
	<div class="clear"></div>
</div>
 <?php else : ?>

	<?php if ( ! comments_open() and !is_page() ) : ?>
		<p class="nocomments"><?php _e('Comments are closed.', 'themezee_lang'); ?></p>
	<?php endif; ?>
<?php endif; ?>

<?php if ( comments_open() ) : ?>
	<?php comment_form(array('comment_notes_after' => '')); ?>
	<div class="clear"></div>
<?php endif; ?>
