I am an expat working in an English company and the girls are being EVIL with me?

you can handle this two different ways. If you are comfortable doing so, I may confront those who are not treating you with proper respect and ask them what the problem is. If that does not work, you should go speak to your supervisor AND the head of your human resources department and let them know what is happening and how it is affecting you. I wish you the best of luck!
