Spacing Issues

Margins on my desktop site look (for the most part) the way I’ve intended them to. However, on my mobile site, there are random indents, larger margins in some places and smaller in others, and just general inconsistency that I can’t seem to solve. I’ve contact my theme’s support and so far have gotten nothing from them but frustration. Site is kfayedesign.com/-wp- Particularly having issues with random indents happens before “About” and “Method” on the About Us page.
