My first self executing function... :)

test.js

(function (window, $) {
	"use strict";
	var document = window.document;

	$(document).ready(function () {
		$('.open-customer-service').children('a[href="#"]').click(function (e) {
			e.preventDefault(); // stop the link from taking us back to #
			$('#customer-service-modal').show();
			window.scrollTo(0, 0);
		});
	});
})(window, jQuery);
