1. This padding is coming from your Joomla template, http://take.ms/ogyaX

2. This margin is also coming from your Joomla template, http://take.ms/BNUgR

3. To be frank with you, I was deciding if we should really help you or not considering that this is not our issue but as always, we try our best to assist in your problems as much as we can. I certainly wish that you stop your hostility and stop blaming us for everything and anything that has happened to your site.

Anyhow, to fix this you can apply the css codes below to fix your template,

body #jsn-promo {
padding-top: 0;
}

body #jsn-promo .jsn-modulecontainer_inner {
margin: 0 !important;
}
