You should still make contact, even if you think your MEP won't do anything. Bad things happen when people don't get involved because of the false assumption that their input doesn't matter.
I have already tried. UKIP's response was a pointed suggestion that I leave the country. If that choice were open to me, I wouldn't be here in the first place.
It's good that you tried. Even though the response was rude, unprofessional, and probably racist, at least you did what you could.
Not overly surprising, though. It's their core belief that all foreigners leave. I asked them once how far back they intended to go in expelling foreigners, since people have been coming here since before the Romans. Nasty party to have to deal with.
It sounds really frustrating to have to deal with, I'm sorry to hear that. :(
