Data storing in the Database, WordPress WooCommerce

I am currently coding the following, and don’t seem to get my database to interact with woocommerce, this is a sign up/register form, so the information basically just needs to be posted to the database so its logged for when the user needs to use it? I have however managed to get it to logged everything such as password/first name etc, but nothing to do with woocommerce such as billing address, here is my code hope you can help!

<div id="content">
<div class="titlebox" ><center><?php the_title(); ?></center></div>

<div class="description">
<center>
<strong><h2>Create an Account</h2></strong>
</center>
</div>
