Help needed to custom cart page

Hi there I wondered if anyone could help me on this:

I am currently updating a business site (to cut a long story short previous person that was looking on this site past away!). Now I am sort of newish to WordPress and all its plugins. I have managed to tweak a few bits and bobs, but I am stuck on trying to update this cart page (for desktop and mobile view). Now you can see that the shipping details have been placed to one side, i would like this fit to width or stretched out bigger. Also when viewed on mobile the list of products area is chopped off the screen.

Now from what i can see this is connected to WooCommerce, using WPBakery Page Builder and Qode Options Bridge Child 1.0.0 I believe most of the settings sit in the Qode Options Bridge Child 1.0.0. but if anyone can help that would be grateful!!!!

thanks!
