This code should work for you.

$top_level_terms = get_terms( 'product_cat', array( 'parent' => 0 ) );
foreach( $top_level_terms as $top_term ) 
{
        $child_terms = get_terms( 'product_cat', array( 'child_of' => $top_term->term_id ));
        //Parent Category Name
        echo '<b>'.$top_term->name .'</b><br>'; 
    $top_id=$top_term->term_id;
    if(count($child_terms)>0)
    {
        foreach ( $child_terms as $child_term ) 
        {
                 $id=$child_term->term_id;
                 //Child category name
                  echo '<b>=>' .$child_term->name .'</b><br>';

            $myposts=get_posts(array(
            'post_type' => 'product',
            'tax_query' => array(
                array(
                'taxonomy' => 'product_cat',
                'field' => 'term_id',
                'terms' => $id)
            ))
                );
echo '<ul>';
        foreach ($myposts as $mypost) {
            //Posts
              echo '<li>'.$mypost->post_title.'</li>' ;

        }echo '</ul>';
        wp_reset_postdata();

        } 
    }
    else
    {
    $myposts=get_posts(array(
                'post_type' => 'product',
                'tax_query' => array(
                    array(
                    'taxonomy' => 'product_cat',
                    'field' => 'term_id',
                    'terms' => $top_id)
                ))
                    );echo '<ul>';
            foreach ($myposts as $mypost) {
                   echo '<li>'.$mypost->post_title.'</li>' ;

        }
echo '</ul>';
     wp_reset_postdata();
    }


}
