Okay, i managed to fix that myself. @kayyyy thank you for trying to help. 
I just played around with code a little, got it working in the first colum. footer-navigtion.tpl [code]{extends file=“parent:frontend/index/footer-navigation.tpl”} {block name=“frontend_index_footer_column_service_hotline”}
Finde uns auf Facebook
{block name=“frontend_index_footer_column_service_hotline_content”}
{/block}
{/block}[/code] index.tpl [code]{extends file=“parent:frontend/index/index.tpl”} {block name=‘frontend_index_after_body’ append}
{/block}[/code] here the code, if someone needs.
