Mobile not working properly

Hello,
I’m having a problem with the mobile version of the theme.
1.Menu is not showing up.
2. There’s a lot of space between the beginning of the page and the header image.
3.Logo is too big on mobile (phone)
4. Contact form is simply weird, on the live composer it looks good but not on the phone itself.
Site is: http://neqaauav.pt

Best Regards
