Hide billing details

Hi!
I’m trying to get rid of the billing details on my checkout page in WooCommerce, and I’ve tried a lot of things, for example testing different codes (found on the net) one by one in my functions.php, and I’ve also tried different plugins which are supposed to remove the billing fields, but nothing works! (Some plugins are able to get rid of some fields, but not all of them). So now I hope that you can help me out! I’m quite new to WP, so do you have any suggestions? You can see the problem here:

Thanks:-)

you will not be able to override the woocommerce/archive-product.php custom template since woocommerce.php has priority over archive-product.php. This is intended to prevent display issues.
