Contact page responsive Layout help

Hi everyone

I am struggling to make my contact page responsive. I’m afraid I’ve fiddled around too much and now I don’t know whats going on.

When I resize the contact page to different size phones, the layout goes all out of line ( logo , heading etc) And when I do make one phone model responsive, the others go out of line. Maybe my default desktop breakpoint is out of sorts?

If anyone could help that would be great.
