Thanks pilot recruit and rusty (again),
I did contact them and I recieved an email today saying exactly that, that they have problems with my english qualification.
Wow, I didn't expect that!
Now I will obviously contact them again and see what can be done about it!
It's all a bit silly really as I've been living and working in english speaking countries for the past five years...
Whatever comes out of it now, I'm very glad I contaced them. Feel much less dumb now ;-)
Thanks again everybody for thoughts and support!
