There is a way you can embed a Facebook page feeds into your Joomla site using the component & plugin JEmbedAll: write down into a Joomla article, module or code the URL like this [ fbpage = https://www.facebook.com/pages/Supravirtual-SRL/ ] (without the spaces). The plugin will recognize the text and it will embed the data into the site.
In the administrator section you can edit this string - you can change its name and the CSS code attached. Using the CSS code you can set the width and height of the embedded Facebook page, the position and other attributes (like the margins).
