Footer Spacing issue

I did a recent update and had the spacing set in the footer to accommodate a longer phone number. It was working and after the update the number was gone so I went back in and replaced the number and it will not show at all. I still have the spacing set in the css. I corrected the php files and still it is found on the far right of the page off the screen.

function tc_colophon_right_block() {
    	echo apply_filters(
    		'tc_colophon_right_block',
		  sprintf('<div class="%1$s"><p class="pull-right"><a class="back-to-top" href="#">(800)844-DISC(3472)</a></p></div>',
    			apply_filters( 'tc_colophon_right_block_class', 'span4 backtop' ),
    			__( 'Back to top' , 'customizr' )
    		)
    	);
	}

Css for the span adjustments

.span4.backtop {
  width: 24%;
	  font-size:22px;

}

.span4.credits {
  width: 36%;
}
